Troubleshooter of Error: Cannot run exe files or install programs

Cannot run exe files or install programs

Whenever I tried to run an exe file, the following message appears:
Windows cannot find 'C:\Windows\regedit.exe'.
Make sure you typed the name correctly, and then try again.
Even though I have checked that regedit.exe exists and is in the folder C:\Windows\
Such message appears when I double-click a exe file or run the program through the search box at the bottom of the start menu.
 
Note:
When I enter the safe mode, I can run some exe files such as  the regedit.exe or msconfig.exe, but not so in normal modeSome programs that I have previous installed can be executed normally, such as Word, Powerpoint, Skype, etc.
Any suggestions of how I could fix this problem?

Hello Howard Fu,
It sounds as if you may have a Virus or malware infection.
Have your run a Antivirus? If not, you can download Microsoft Security Essentials.
Clickhere for a link.

Once you have checked for virus, if you are still having a problem, click on the following article number. 
KB Article ID: 950505 - When you run an .exe file on a Windows Vista-based or Windows 7-based computer, the file may start a different program
I would also suggest you run SFC /scannow to see if you have any corrupt system files.
Click Start
Type: CMD, from the results, right click CMD
Click 'Run as Administrator'
At the Command Prompt, type: sfc /scannow

This will check for any integrity violations and fix any corrupted operating system files.

Restart your system.
See: KB Article ID: 929833 -How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
