I posted this in Vista ng but they don't seem to get the participation this ng gets and I don't see some of the talent there that's here. So, if it's ok here goes: HP laptop running Vista Home Premium 64 service pack 2, AMD 2.2 GHz dual core, 4 GB RAM, 175 GB free on HD. I've tried installing a couple software, the first was a freebie from a furniture company and the latest is MS VISIO 2010 BETA and I get "error 1606 could not access network location %APPDATA%/" I tried all the suggestions concerning registry concerns on MS knowledge base and no change. Ran the auto-fix available on MS knowledge base and no help. Went back through the registry entries again and same. Downloaded Advanced System Optimizer, ran it and no change. Googled the error and almost everything points to a registry problem and either directs to knowledge base or repeats the steps listed there. I have Office 2007 retail plus Office 2010 BETA installed so I thought that might be causing the problem. Tried to uninstall 2007 and got the same error message. I don't know if this is related but when I create a new folder it will only let me name it "new folder". I can delete it, but I can't give it any other name or rename it, it just goes back to new folder. Any help is appreciated, I am not against looking at the registry again as sometimes a fresh set of eyes will see something, so if you have a thought fire away. Thanks, Dave P.S. Anyone have a Windows 7 64 Bit upgrade, preferably Home Premium edition, for sale at a really good price I'm interested.
