I could not install Flash 10.1.102.64 on Windows XP Professional, Service Pack 3, 32 bit. The install appeared to work OK, but Flash was not detected. I tried several times to use the automatic install but had the same results. I even used Adobe's stand alone uninstaller, deleted the Flash folder from Program Files/Adobe, cleaned up the Register with CCleaner, rebooted twice and then installed using Adobe's stand alone installer! Flash still didn't work!! I finally uninstalled, deleted flash folders, and cleaned the registry again. This time I went to http://kb2.adobe.com/cps/142/tn_14266.html, selected an archived version 10 and installed it. Adobe Flash has been working fine since. I still don't know why version 10.1.102.64 wouldn't install.
