Error: All Programs Open In Adobe Reader

When you double-click an .EXE file, the program may not launch, instead it open in Adobe Reader and displaying an error.

This happens when you've installed Adobe Reader, it has changed the EXE file association in registry to open with it. You need to restore this registry value into default to make it working again.

Fix:

Click on Start > Run > type in --> regedit <-- navigate to:

HKEY_CLASSES_ROOT\.exe

In the right pane, edit the value on each key to:

(Default) = exefile
Content Type = application/x-msdownload

In Registry Editor, it looks like this:

Note: The value for "Content Type" on error computer is "AcroRD32.exe" or similar.

Or:

You can create a registry file for fast fixing by copy and paste below text into Notepad, save it as --> fix.reg <-- choose "All Files" in "Save as type" and save it to your Desktop. Double click the file to run it.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.exe]
@="exefile"
"Content Type"="application/x-msdownload"

Restart your computer for changes to take effect.
