Software Installation Program for verifing the installation???

One of my friend is doing his computer project and he has one problem. the problem is that"If we are installing any software then is it possible to make a program in C++ or VB that can crosscheck that all files under thE folder of software are installed sucessfully?"If anyone has any idea than please tell.

when it comes to installation,well i got only one word for you, check out nsis i.e http://nsis.sourceforge.net/Main_Page it should sort out everything for you.

I don't want a software installer but the need is of a program to check that the software installer has been installed the program correctly or not.

Uhm, surely all you do is make the installer program catch any errors? If the installer can't write a file because of lacking permissions or anything like that you can catch that during the installation in the code, you don't need to check when you're done installing, do you?

And if you want to check the integrity of the installer package you could perform some sort of hash value check on the install package before starting to install.
