I developed a VB windows based application using vs 2008, packaged it to be used in dotnet 2.0 because 3.5 needs internet.

After installation on a client machine, if I click at it later it will demand me to re-install it again that I should provide Original msi file otherwise it wont work.
Or Maybe I made correction and replace the existing .exe with the one in the program file, the system will request for another re-installation in which case it will renew everything just as if I have made another new installation from old msi.

Please help!
