I am having difficulties updating pscan on my Windows Vista computer, which used to work perfectly well. I downloaded pscanloader.exe but after double-clicking and accepting the Licence Agreement, it says "Download failed. Cannot continue." and closes down. I have made sure that McAfee virus scanner does not block the installation process. Can anyone advise what I can do?

I assume that it may be that the Windows software is too far out of date and can no longer support the application? If this is the case, how do I delete it from the computer so that I can install it on another (the PSCAN subscription allows it to be installed on up to 2 computers)?

Please help!!

Thanks,
Michael
