Jim, thanks for your reply. FWIW, I have WinXP Pro but do not have a \windows\installer folder. I did a search on my hard drive for msi files and found them sprinkled all over, mostly under various subfolders under \Program Files. Hope this doesn't indicate a problem. Seems more organized to have them in a specific folder.
IAC, none of the files I found seemed to be the one for the Beta, so I'll try to reinstall it this evening and then remove it.
Thanks,
Del
