OK, Here is the latest.

I can Install but something is definitely wrong. I am rebuilding two computers one 32 bit and one 64 bit.

After installing the service packs, the first step is to install MBAM and Avast. BOTH CLEAN COMPUTERS will install but not start services.

After running the clean uninstall program from safe mode, the only way to get to INSTALL IS FROM SAFE MODE.

msconfig / BOOT / Select Safe Mode. (OR F8 if you are quick enough)

Hope they fix this soon!
