Thanks for the suggestions
I didn't try the support for the "Service Pack 1 Setup
Canceled" as I am not receiving this error.
I have looked in the log.
There is no reference to the registry section
HKEY_CLASSES_ROOT in the log, and I am not using NTFS.
The last few lines of the log are listed below. The
applicable error seems to be "INF_REGISTRY FAILED",
however this is undocumented by Microsoft so I do not
know what to do next
