Thanks for your reply.
I run a nightly schedule of SuperAntiSpyware, Malwarebytes, SpyBot, Crap Cleaner and MSE. All show nothing . I also ran MS Malicious after the first failed upgrade install of MSE.
The reason that MSE will not upgrade is it can not find a file that needs to complete the job. See post #1 image. It looks for u:\21bcc7df7a14f5430a4b\x86\ which is not there.
Upgrading to 64 bit will solve the problem.
