windows 7 .exe files opening with adobe reader

Hi manoj84,

Welcome to Microsoft Answers community.
 
Many times windows face problems while opening .EXE files.

• The EXE file opens in Notepad.
• EXE file opens in some other installed programs.
• Windows displays "Open With" dialog box to choose the program.
• Windows shows error message, "Windows cannot find .exe file. Make sure you typed the name correctly".
• Most of the times it happens when you accidentally change .Exe file type settings from Folder Options. Sometimes it might happen due to virus.

Anyway no need to worry. Here is a solution which will fix this annoying problem:

1. Open Command Prompt by typing command in RUN dialog box.
2. Now provide following command:

cd\windows

3. It'll activate Windows folder. Now provide following command to open Registry Editor:

regedit

4. Now goto following key:

HKEY_CLASSES_ROOT\.exe
In right-side pane, change value of Default key to exefile

5. Now goto:

HKEY_CLASSES_ROOT\exefile\shell\open\command
In right-side pane, change value of Default key to:
"%1" %*

6. Thats it. Now exit Registry Editor and restart your Windows. Now you should be able to open EXE files without any problem.
