Windows Cannot Locate Webfldrs.Msi

Win XP Pro, when I try to find webfldrs.msi the file is missing from system32 folder. I downloaded the installer from Microsoft and it says that it has been installed. When I check again, the file is still not there. Any ideas? I think I need to reinstall dll files. I do not have a repair disk. This computer is a friend’s and it appears to have been configured in vietnam, but it was purchased in Thailand. Not sure the international part has anything to do with it. Given the origin it is possible the Windows OS is not authentic to begin with, but with out disks I am unable to do anything about it.

The problem I am trying to fix may have nothing to do with this, but when I boot the computer it hangs on a black screen with a movable cursor for about 5 minutes and then finally loads windows. Event viewer shows several services not loading which was leading me to think the dll’s are corrupt or missing. I wasn’t sure if that could cause the black screen.

When it was set up they apparently did not set up user accounts. So the primary Admin account is being used as the only user on the computer. Not sure if it could be a corrupt user file for the primary… not sure how that can be fixed (without losing data etc.) if that is the problem.

So I can’t simply reload. I can’t access webfldrs.msi to reload the dll’s. And I don’t know how to handle the Admin. Meanwhile booting is a royal pain. I think the main cause could have been trojan related as I had to clean with comodo, eset and malwarebytes to remove many many instances of trojans and spyware.
