I have a similar problem installing Flash 24.0.0.194 on Windows 7 64-bit Enterprise. Both ActiveX and NPAPI versions install to approximately 50% in about 2 seconds (determined 50% using interactive install) and then hang at 50% for 5 to 6 minutes then eventually complete successfully. I started with my usual silent install script, then tried interactive by clicking on the .msi files. I've done this several times now with the same results. Outcome is the same whether a previous version is installed or uninstalled before running the new install. NPAPI install: InstallPlugin_20_0_0_194.exe *32 runs at 0 to 2% CPU during the 5 minute pause, then InstallFlashPlayer.exe kicks in in the end before the install completes. ActiveX install: InstallAX_24_0_0_194.exe *32 runs at 0 to 2% CPU during the 5 minute pause, then InstallFlashPlayer.exe kicks in in the end before the install completes. I've downloaded the .msi files from the link provided in the Runtime Software Distribution License Agreement. I will send the log files if requested, but I get the feeling a fixed version will be available soon. Every so many releases of Flash the installer is just crapped up. Thank you.
