Illegal operation attempted on a registry key that has been marked for deletion

[kinook]

I'm not sure. We have built the build.bld sample continuously for several days on a Windows Server 2008 R2 Datacenter machine (clean install + VBP 7.7, Windows Update disabled, VMware guest) and have not encountered any errors or hangs. There must be something unique about this machine that is a factor somehow. We would need to be able to reproduce the problem to investigate further. Could you try it on a different machine or give us access to the problem machine?
