Win XP, SP3. Downloaded new version os installer (install_flashplayer11x32_mssd_aih.exe), run it. The downloaded file deletes itself (I hate this behaviour), run another exe from temp dir. My firewall asks sveral time for installer access, access is granted, and nothing more happens. The process lives, but does nothing. No further questions or progress bar, just hangs in process list. The same with firewall disabled.
Tried several times (and downloaded several times because of autodeleting, really thanks).
