FF 30 has failed to run for me on Win2k; launching the executable fails with "firefox.exe is not a valid Win32 application." I've tried installing FF12 and upgrading to 30 by modifying the update URL, as well as using the portable version, both give the same error. May I ask how you're running FF 30? Is there some kind of compatibility program to use? Yes, Uurollup. It requires the MS official Service Pack 4 and Update Rollup 1. Download it from here:https://drive.google.com/folderview?id=0Bw_nt4aAJIoPOUZpTFJHckdPMVE&tid=0Bw_nt4aAJIoPWWNBay13dTlXOWs#list . The included Application Compatibility Launcher is enough to install. Scroll down to very bottom and download that file. Hmm, the disc I used installed the SP4 version by default, and from there I installed Update Rollup 1, followed by UURollup 2, followed up USP5.1. Even when using appcomp.cmd, the browser itself says it's not a valid Win32 application, and the installer says it requires XP SP2 or newer. Did I install my updates wrong? Do I need to start over?
