I tried install Flash player 18 (offline and online installer) for mozilla firefox on my PC: athlon xp 2600+ (non SSE2), 3GB DDR, XP SP3, Firefox 39.0 and can not install (update), flash player gets me error message and ath end instalation can not be finished. Updating works OK with flash player 17 and olders, is there problem with my older non SSE2 Athlon XP CPU or something else ? Please Help.

I don't know about any such restriction; can you try to run the offline installers from https://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#ma in-pars_text_4
If it still fails, please post the contents of the FlashInstall.log file in C:\Windows\system32\Macromed\Flash
Re-reading your post made me realize that you have already tried the offline installer. So please post the FlashInstall.log file (the lat 100 lines or so).
my mistake, i did not tried ofline. Ofline installer works ok. Thank you.
