Any hope here?
I am running XP pro with all updates.  I am running into a problem trying to download the latest Firefox browser and an antivirus software program.  I keep encountering the "Not a valid Win32 application" message.
Am I stuck in the last CENTURY or is there a way I can upgrade my system to a 64 bit OS?  ThanksYou need to download the 32-bit versions of whatever software you're trying to install if you're running a 32-bit OS.

If they are 64-bit installers or if the 32-bit installer is a corrupted or incomplete download, you will GET this message.Thank you quaxo.
Appreciate the information.
Unfortunately the latest web browser from Firefox does not give me a CHOICE as to which os version I can download.
Same with the AVG file I am trying to download for virus and malware PROTECTION.
I found the post that proceeded mine about how to determine which type of system (32 bit or 64 bit) to also be very informative.
I may be at one of those crossroads with respect to investing into a newer pc.
Thanks again for your insights.
