Причины возникновения ошибки

Иконка вопрос причины

EXE-файлы могут не запускаться или выдавать ошибки, если:

  • в реестре системы изменен параметр, отвечающий за ассоциацию программы с файлом;
  • антивирусная программа блокирует доступ к приложению, ошибочно воспринимая его как вирус, или файл действительно заражен;
  • некорректное функционирование системных компонентов.

Варианты решения проблемы

Иконка Методы список

В зависимости от того, чем вызвана неполадка, можно воспользоваться различными методами её устранения. В первую очередь следует проверить правильность ассоциации исполняемых файлов в реестре, а если это не решит проблему, то запустить проверку системных файлов и сканирование компьютера на вирусы. Также возможно, что ваше антивирусное приложение блокирует запуск программы. Рассмотрим каждую из ситуаций в подробностях. 

Вариант №1: Проверка ассоциации в реестре системы

Иконка Реестр regedit

Чаще всего ошибки при запуске EXE файлов являются следствием нарушения ассоциации формата в реестре операционной системы. Чтобы исправить ошибку, нам потребуется проделать следующие шаги:  

  1. Вызываем диалоговое окно «Выполнить», воспользовавшись клавиатурной комбинацией «Win+R».
  2. Далее вводим туда команду regedit и кликаем по кнопке «ОК».

    regedit Запуск Редактор реестра меню Выполнить

    Запускаем редактор реестра

  3. На экране появится «Редактор реестра». Нам нужно будет пройти по следующему адресу: HKEY_CLASSES_ROOT\.exe
  4. В правой части ищем значение «По умолчанию» и открываем его настройки, кликнув по строке дважды.
  5. Появится маленькое окошко, куда нужно будет вписать значение exefile и после этого кликнуть по кнопке «ОК».

    HKEY_CLASSES_ROOT.exe Редактор реестра

    Проверяем и при надобности изменяем настройку

  6. После внесения изменений переходим по адресу:  HKEY_CLASSES_ROOT\exefile\shell\open\command
  7. Тут также ищем справа параметр «По умолчанию» и открываем его.
  8. Значение должно выглядеть следующим образом 

Если в параметре указаны другие знаки, удалите их и впишите правильные.

Реестр HKEY_CLASSES_ROOTexefileshellopencommand

Проверяем еще один параметр

Изменив значение, его также потребуется вписать, пройдя по следующим адресам: HKEY_CLASSES_ROOT\exefile\shell\open и HKEY_CLASSES_ROOT\exefile. 

Делается это аналогично пунктам 7-8.

После проделанных операций закрываем реестр и перезагружаем компьютер.

Вариант №2: Проверка целостности системных файлов

Иконка системный файл

Если установка правильных параметров в реестре системы не принесла желаемого результата, то можно проверить работоспособность системных файлов Windows. Для этого нам нужно будет сделать следующее:

  1. Запускаем «Командную строку» из стартового меню с привилегиями администратора.

    Запуск от администратора Командная строка

    Запускаем командную строку

  2. В окно приложения вводим команду sfc /scannow и нажимаем «Enter».

    sfc scannow Проверка системных файлов

    Запускаем проверку системных файлов

    Windows начнет проверку системных файлов и в случае обнаружения ошибок устранит их.

После завершения операции перезагружаем компьютер.

Вариант №3: Очистка компьютера от вирусов

Иконка вирус бомба

Если у вас на компьютере появился вирус, то он также может быть причиной того, что программы не запускаются. Чтобы удалить его из системы, удобнее всего будет использовать бесплатные сканеры, такие как Kaspersky Virus Removal Tool.

Проверка на вирусы Kaspersky Virus Removal Tool

Интерфейс сканера Kaspersky Virus Removal Tool

Другой вариант — Dr.Web CureIt.

Запуск сканирования Dr Web СureIt

Главное окно программы Dr.Web CureIt

На этом наша статья подошла к концу. Теперь вы знаете, как можно устранить неполадку, когда на вашем компьютере не запускаются EXE-файлы. Иногда запуск приложения может быть заблокирован установленным у вас антивирусом – в таком случае потребуется просто его отключить, предварительно убедившись в том, что запускаемое приложение не опасно. 

Нарушение ассоциации с исполняемыми exe файлами

Возвращаем возможность запуска исполняемого файла

Для того, чтобы вернуть все на свои места, следует использовать следующий reg файл (вложенный в zip-архив), после использования которого нужно перезагрузить компьютер.

The simplest method for setting a profile is to simply edit Chrome’s shortcut and add the command-line parameter --profile-directory="default":

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Default"

The downside with this approach is that it only affects the shortcut itself. If Chrome is your default browser, and another application opens a page, this will have no effect. Similarly, if you associate a local file extension with Chrome, it will not affect which profile is selected when opening that file type from Windows Explorer.

The fix for this is to specify the profile to use in the Windows Registry. In order for this to work for both mapped extensions and shell execution, we need to make a change in two different places:

The default value for both of these are the same:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -- "%1"

Just as with the Shortcut method discussed previously, we simply need to add the --profile-directory="default" switch. One difference, however, it that here we need to add it between "chrome.exe" and -- "%1":

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Default" -- "%1"

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\Applications\chrome.exe\shell\open\command]

"ProgId"="FirefoxURL"

Windows Registry Editor Version 5.00

"ProgId"="ChromeHTML"

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice]
"ProgId"="IE.HTTP"

The Long Answer

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations

What I’m talking about here is what you’re changing when you go to the Default Programs section of the Control Panel to set a browser:

Default Programs for Protocols in the Control Panel

To configure this directly in the registry, let’s first inspect that’s already there. In this screenshot I’ve navigated to that key in regedit.exe, and Chrome is my default browser, designated by the ChromeHTML ProgId value.

Navigating to the UrlAssociations subkey in regedit

Now it’s just a matter of determining what to use for Firefox, IE, and any other browser you may want to switch to. If you wanted to determine this programmatically, you could do so by digging into the Capabilities key of the browser registration, found here for Firefox:

HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\FIREFOX.EXE\Capabilities\URLAssociations

HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet is where all the browsers are listed, and each one should have the above structure.

Navigating to the Capabilities key in regedit

You can see from inspection that if I wanted to switch to Firefox, I’d use the FirefoxURL ProgId value back up in UrlAssociations.

All we need to do is change that key value to FirefoxURL, and now links open in Firefox. After doing so you can either click a link or double check in the control panel that the right default is registered:

Double checking the default program in the Control Panel

Now if you’ve been paying close attention, you might have noticed a couple flaws with all of this:

  1. IE doesn’t have a URLAssociations subkey under it’s browser registration in StartMenuInternet, so where does the ProgId value come from? Answer: I don’t know, at least not without more research. It may be hardcoded or found in another key I haven’t found yet.

  2. Firefox’s ProgId’s under it’s URLAssociations are FirefoxURL, but when you click to register in the options in the browser itself, it uses FirefoxHTML as the ProgId instead! Why? Again, I don’t know. They both work because they both exist and point to Firefox. Maybe it’s intentional, but it’s probably just a bug with no effect.

I need to find out where in Windows registry email default app is stored so I can adjust the link to open with the page I want it to but I can’t find it, there is so many different locations. This is the link I want to use which should work: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -- "https://mail.google.com"

Please let me know where Windows 10 stores its default email app in its registry?

  • Where Windows 10 stores default email app in its registry?

    This is the caption of the original question.
    Default email app in Windows 10 is an App which handles mailto: protocol. It’s actually not supposed to open Inbox, but Write a New Email form — by opening a new page/window to start writing an email.

  • How to change Hardware Keys association?

    This is the rest of the question, or question number two.
    One of the buttons on your keyboard was defined as Write New Email, which was done by calling the Default Email App using mailto: protocol.

But calling mailto: protocol wasn’t opening the Write New Email form, neither the Inbox, or an Email App. And that’s a question number three.

  • Why is Chrome not opening Write new e-mail form using mailto protocol?

    Because Chrome will ignore it, unless it’s explicitly allowed in Chrome’s Options.

All three answers in detail

  • Hardware keys association

    What action should be taken upon pressing of a special HW key
    HW button could be a dedicated button, or a Fn+F2 combination as in Asker’s case.
    Registry settings are under:
    HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Appkey
    Key 15 represents settings for Email button
    Value names could be:

    • «ShellExecute» — its value is a filename to be executed
      e.g. «calc.exe» or chrome.exe with corrent path and possible arguments
    • «Association» — points to a shell association object
      which is a name of a Key under HKEY_CLASSES_ROOT
      e.g. txtfile would open Notepad, or as in our case mailto would open an App associated with mailto protocol.

    To open a Write new e-mail using mailto association. This was the default behavior on the Asker’s computer: 

    REGEDIT4
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Appkey\15]
"Association"="mailto"

    To open an e-mail app, or browser with an e-mail’s Inbox, you can use shell execute with proper command. This is what Asker desired and his solution would work for this case.

    ShellExecute "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -- "https://mail.google.com"

    or in a form of a .reg file 

    REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\15]
"ShellExecute"="\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\" -- \"https://mail.google.com\""

    To open Gmail App — Chrome’s App in it’s dedicated window.

    REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\15]
"ShellExecute"="\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\" --app-id=pjkljhegncpnkpknbcohdijeoejaedia"

    for this last one to work, you also need to have the Gmail App installed in Chrome, and need to enabled «Open As Window» in right-click menu on the Gmail App in Chrome.

  • Default e-mail App for mailto protocol

    Which program is handling the Write New Email call
    for example when you click on send e-mail to developer on some Program’s About menu or on various other places in Windows or by clicking an email link in a document or a web page.
    The selection can only be done using the Choose an app dialog from Windows Settings or Open as command.

    Settings - Default Apps

    Would be less confusing if the settings was saying Write an Email and not just Email
    I don’t think that there is a separate setting in the Windows interface for an App which would open Inbox.

    To troubleshoot a problem with default mailto association, you can delete mailto Keys from under all of these locations, except LOCAL_MACHINE.
    Windows will re-create them on next use of the mailto protocol.

  • There is no default action for mailto: links inside Chrome defined.

    • The default way to turn this on should be to «Click on the eye in the address bar.» while on gmail.com web page and selecting Use Gmail.
      But sometimes, there is no «eye»

    • Turn mailto: handler on manually.
      Go to Chrome Settings — Privacy — Content Settings — Handlers — Manage Handlers,
      or enter address: chrome://settings/handlers
      then remove Ignored protocol handlers and switch Active protocol handlers to mail.google.com

      Protocol handlers

[HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\Google Chrome\Capabilities\URLAssociations]
"mailto"="ChromeMAILTO"

      or, if you prefer to have it open as an Chrome App, in dedicated window:

      REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ChromeMAILTO\Application]
"ApplicationName"="Google Chrome mailto"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ChromeMAILTO\shell\open\command]
@="\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\" --app=\"https://mail.google.com/mail?extsrc=mailto&url=%1\""

[HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\Google Chrome\Capabilities\URLAssociations]
"mailto"="ChromeMAILTO"

      Now select Google Chrome mailto as the Default Email app
      enter image description here

    I didn’t test if Chrome update would not break this work-around

Below is a quote from that link

Internet Key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Appkey\7
«Association»=»http» ; Change the string value «http»

Calculator Key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18
«ShellExecute»=»calc.exe»; Change the string value «calc.exe»

Email Key:

«ApplicationPath» = «C:\Program
File(x86)\Cyberlink\PowerDVD9\PowerDVD9.exe»; Change the string value
«C:\Program File(x86)\Cyberlink\PowerDVD9\PowerDVD9.exe»

But for little more explaining this is what I did:

Adding a program to any protocol

  1. Open the Registry Editor.
  2. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet.
  3. Find the program (e.g. your browser) you wish to use (you must have already opened it).
  4. Add mailto to the URLAssociations.
  5. Do not reboot or log off.
  6. Close/rReopen the Settings secondary Control Panel and the program will be listed.
  7. Edit your program’s internal settings.

Details

Windows 10 needs to know what protocols a program supports in order to list the program for the protocol. Thankfully it’s fairly simple with a minor complication of having a hash (likely for tracking) involved. I am guessing that the hash is generated per install (just a guess) so you likely can’t dump it in to your windows-10-fix-all-junk.reg file that you run after yet another install of Windows 10.

Blood and bloody hashes!

Mat, I use Waterfox as my default browser because I can (actually) customize it. If you need to create all the registry settings but you don’t know where to find the hash well go look for your program in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\, for Waterfox it was:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Waterfox\TaskBarIDs

Register all the things!

With the hash replaced by stars here is a registry dump (more than needed):

The registry key it alters should be:

HKEY_CLASSES_ROOT\ChromeHTML\shell\open\command
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\mailto
