I have Windows XP on a Sony Vaio, model VGN-FS640. When I click on Add or Remove Programs, I get this message: Windows cannot find 'C:WINDOWS\system 32\rundll32.exe'. Make sure you typed the name correctly and then try again. Then it discusses searching for a file. Until recently I have been able to use Add or Remove. The only thing I have done recently that I can think of is use Spyware Detector and Reg. Cure. At the same time, another problem developed, which I'm including, as maybe they are related: I have Belarc Advisor on my computer. I was going to open it, but I got this message under Sharing Session title, "The destination address is not valid. Check the address and try again." Error 0x80ee0012
I would appreciate any help that you can give me. I am older and learned on a Mac, so it seems that if it can go wrong on a PC, it does for me! I need all the help I can get. Thank you.
