10.2 Startup Hang time?

Problem: On startup, Arcmap hangs for about 90 seconds with arcmap splashscreen stuck on "Finalizing Installation". It seems to be profile specific. Recreating my profile provided a temporary fix but the issue came back. Full uninstall/reinstall of arcmap had no effect. Is there any particular place in the user's profile folder that may be contributing to this issue?

Thanks for the ideas!
