It appears that Windows Easy Transfer locks up COM+ application catalog. Other COM+ applications suffer from this. If you used Windows Easy Transfer (EWT), please try following solution we found

Quote:The solution to restore the broken MSDTC/COM+ that worked for me was to use Easy File Transfer tool again?! (though I kind of promissed myself not to use it again :) ) to export the settings from a healthy Win 7 x64 system and import them on my broken system.
I only selected for migration the Shared Items -> Windows Settings from another (healthy) Win 7 x64 system, and after restart everything was working again as expected.
We are likely to get rid of reliance on COM+ in the next version. COM+ is currently the only consistent source of UWS installation failures.
