Hi, We have tried this at least with Windows 2008 64-bit server and the problem is very reproducible (multiple systems): 1. Install 8.3 on some non-C drive (say E:\) 2. Run the 8.4.1 installer to upgrade this install > it appears that the 8.4.1 doesn't realize 8.3 is even installed Result: Installation fails with a permission problem. It seems certain files from 8.3 are not able to be deleted. When I manually try to delete them, even with the Administrator user, it fails. I ultimately needed to take ownership and then give Full Control before I was allowed to delete them. There is no problem with this upgrade on the C:\ drive.
