And you want to run an out-of-date version of Firefox with publicly disclosed security vulnerabilities.

Why???

With respect to the Adobe full installer not running, have you shut down Windows and started it up again since that problem first occurred? Sometimes when the Windows installer has accumulated a number of deferred updates (the kind that happen at shutdown and startup), it just stops working.

If that doesn't help, your Windows installation may be damaged. You could try the System File Checker.

Thanks for your reply, but sorry it isn't helpful

I face this issue from a few months by the first link above in my question, and I solved it by searching in adobe site and found the second link, but the files from it have stopped working for one month, I search again in mozilla site and found the third link in answer for same issue "that files didn't run-and I think you who provide this link". Now All link has files that don't run, So what can I do?!!!!!. I don't refuse the updates but it must work to use it !!!!!!!!!!

Note: I have tried before to setup the different setup files of flash player on another windows and downloaded them again on another windows and also no file was run. So the problem doesn't in my windows files. and as I said before when extract any file it doesn't have exe file. and also the adobe flash uninstaller file doesn't work, I remove it many times by windows add/remove and delete all files & folders manually "system 32 & application data & all temp files and folders" then try to install it again but no change & same result.
