Thanks for your prompt response. Actually, I solved the problem after posting. When I got to the "Ready to Install" dialog, in the Task Manager, there were 4 instances of msiexec.exe running. I experimented with deleting 3 of them. At first, I killed the whole install, but finally I deleting the correct three, and the install ran to completion.
