Ed, I would have said Yes until you said that you (correctly) have all the ST2 and XT2 files in the /BB folder with the main program, yet get that error of files not found. Likewise, the failure of a new install of an older BIAB version that used to work 'points' (pun intended) to a corrupted file system.

Maybe run CHKDSK /F on the boot drive? Back up any data first. The worst possible case could still be solved by reformatting the drive and reinstalling Windows then your applications.
