Better re-install support

After a windows update I had an issue where the installer wouldn't properly remove the DLLs in the Backup folder, and this eventually caused the runtime to crash on launch. After i had unstalled the software, manually remove the dlls, and reinstall, it would work properly (finally). The installer did report that it couldn't write to the Backup folder for 1 DLL, but it wasn't clear this was actually a critical error (as the software didn't work).

I guess this is related to WOW16 support? So what were the filenames of the files affected? wow32.dll and/or user.exe ? Because these files are shipped with Windows and just contain useless stub code, thus crashing the NTVDM when they are not replaced with the proper copies from NTVDMx64 and may come back from original versions i.e. with a sfc check or maybe also an update. But as you didn't specify filenames of files affected, this is just a guess, so further information is needed.

I recall something like com... Being the one that was not being overwritten because it was in use.

compobj.dll from OLE2 libraries?
