I'm still using adobe reader 6 (which came with my computer) because no later version has ever successfully installed. I'm running Windows XP 5.1 with SP3. When I try to install reader 9, I get a message that states the download manager is being installed. After that, nothing happens. I get no further messages and my cpu is 99% system idle task. The desktop and start menu don't contain a download manager icon or a reader 9 icon. I can't find the download manager in any directory, but the control panel add/remove programs panel says the download manager is installed. I have the exact same problem with the flash player. Can anybody help?
I suggest that you uninstall version 6 first, then download and run the installer without download manager http://ardownload.adobe.com/pub/adobe/reader/win/9.x/9.1/enu/AdbeRdr910_en_US.exe
When then installation is complete, download the 9.1.2 patch http://ardownload.adobe.com/pub/adobe/reader/win/9.x/9.1.2/misc/AdbeRdrUpd912_all_incr.msp
