This is something I fell victim about 18 months ago, pre-SP1 for Windows SharePoint Services, and I'd forgotten about until the recent release of SP2 for both WSS and SPS. By the time I had resolved the problem and discussed it with the Microsoft Escalation Engineer we had standing by, SP1 was already in testing. It was said that a "fix" may not make that service pack. So, it was worked around and was duly forgotten until now -- the release of SP2 -- and so I decided to see if it had been "fixed."

orError 5003. Regsvcs failed for assembly c:\program files\Microsoft Biztalk Server 2004\Microsoft.Biztalk.Deployment.dll. Return code 1. (BizTalk SP1)

I ran into the above error while installing BizTalk 2004 dev/sdk components onto my windows xp/sp2 box and spent a few hours debugging the problem and managed to find a workaround. The problem stems from overly tight default permissions on keys created under HKLM\software\classes during the install.
