Hello, Can anybody help me that, how to check, perticular files have already installed or not in local system during installation of desktop application. Actually i've created a desktop application. Now for that application, some microsoft.sqlserver files must be installed in the local system.

Hi Sun, Thanx for reply. But i think, u didn't got my point. Actually i want that as soon as my application installed firts time on the user's PC, there should be some flag entry of that perticular date, and after 30 days, if user want to run that application, then there should be popup some alert that your taril period has been expired. Plz purchase this s/w for further use. One more thing that in my application there is no any login section and no Data base. So, please help me accordingly... :( reply asap.. Thanx
