Not able to install .exe files, receiving an odd error

Hello
The patch of duty 4 game I downloaded in couples of days ago, but I could not install it, the similar applies while I attempt to install Google Earth
I receive the following error when I click on EXE file

InstallShield
Command line parameters:
/L language ID
/S Hide initializing dialog. For silent mode use: /S
/V/qn.
/V parameters to MsiExec.exe
/UA<url to InstMsiA.exe>
/UW<url to InstMsiA.exe>
/UM<url to msi package>
Ok
Anything didn't occur, when I click on the button of ok.
What is happening over here, I feel that somebody may have modified on my system
Your reply will be an honour for me
Thank you
