Yeah, I got that too. Its a nice program and seems to do a good job.(hasn't caused any problems on any machine of mine yet, so I'm happy.)
Well when I installed it, it was finding 170 entries. I've been gradually deleting them and have now been able to delete all invalid entries with no ill effect (and it was invaluable when doing a clean install of OpenOffice recently - about 50 OO reg entries after uninstall).
Only other vnu download I've kept is Ashampoo Burning Studio which is quite good. True Image was one I missed out on (didn't download in time)
