Hi, I have this exact same problem stalling at 25% so am interested in any fix you get. I'm running Windows 7 Pro SP1. This is a new build with little else on it.
Hi, I had the same problem.
The problems is that the previous install was not properly uninstall.
To solve the problem I deleted all about McAfee from registry and I deleted al folders mcafee.
After that install worked.
