I downloaded Version 3.01.1 of Firefox from Mozilla in order to replace Version 3.5, which was malfunctioning with graphics problems. However, I could not istall it as I was given the message that the downloaded file was from an Unknown Publisher and that there was no digital signature or that the signature was invalid. It asked me if I wanted to install anyway so I said yes. However it would not execute and said it would notify MSft of the problem.
I've tried downloading other files, Avast for example, and got the same message(s). I went to tools/internet options/Advanced/Security and checked "Allow software to run or install even if the signature is invalid" and unchecked "Check for sinatures on downloaded programs". This didn't work either.
I would appreciate any help on this.
