Not me. Just finished installing SP5 on my home XP x32 & works Win7 x64 systems.
What problems are you having?
Installed it last night and all is well. Are you trying an update or complete reinstall.
I am having a problem too. It will not install. Logged service.
What kind of problems? Are you installing it as an Admin Image or just an individual installation?
I am having some strange phenomenon happening on my 2012 Admin Image this year and currently SP5 will not install on any users PC. Prior to releasing 2012 Sp3 to our users I seen some of these problems, but now the problem is on a much larger scale.
