I just downloaded and installed winfix 10 and extracted the files.
I clicked on the executable file and message came up and asked if I wanted to continue. I indicated yes.....but nothing appeared.
FixWin may fail to run if you have modified Windows Image using third-party tools, as it may miss some core components required for FixWin to run and thus be the cause of failure.
Have you changed the Windows Image using some other third-party software?
