I just bought a used computer and it appears there is an issue. I am unable to download any new programs. I was able to update Windows with SP2 and all of the security updates. Whenever I try and download a new program (AVG, CCleaner, IE,etc.) It shows that it is downloading, but when I try to open the file it shows O bytes for the file size and gives the following error "C:\users\newmachine\desktop\(program name)example is mseinstall.exe is not a valid win32 application. I tried changing the download folder to the desktop, but I get the same error. Also, this is all being downloaded in Firefox, as I cannot locate Internet Explorer on the computer or download it. I used F-secure online virus scan, since there is only windows antivirus tools currently in place and it came up clean. Here are my system specs, hopefully someone can help.
HP Pavillion dv6000 AMD Turion x2 3gigs ram 32 bit windows vista home premium.
