Iceweasel 54 is not working on Windows XP.
(Iceweasel-v54.0.zh_CN_win32_vc14_pgo.7z)
1) executables are still marked to be vista+ only
2) mozglue.dll , mozavutil.dll , lgpllibs.dll, mozavcodec.dll, d3dcompiler47.dll, xul.dll try to import vista+ stuff
3) K32GetModuleInformation not found... XPCOM? (dynamic loaded) again vista+
Iceweasel 53.1.0 will be the last version for Windows XP.
It's very, very hard to support for the Windows XP in future releases.
I have changed more than 3000 sources files and re-compile, But it crashed on the Windows XP.
I need a lot of time to do the stability testing, I need a faster PC.
But when I had it, i think Windows XP is completely dead.
A pity for that, but well I'm understand.
Anyway I hope that you find a way to fix it :) although i understand is an work really hard to do.
Thank you very much for you reply.
Best regards.
