I assume you've just downloaded the latest version of Firefox, and when running the .exe installer, you get the message?

If yes, then delete the downloaded .exe file, and re-download it and try again - most likely your download is corrupted...

Hope this helps.

Also make sure you didn't download an x64 only version (of which I've only seen a couple around mind!)

Thanks, Tightscot's suggestion worked. I never thought of downloading it again.
