I have been trying to install Flash 11 on my windows 7, 64 bit system for firefox. The download works fine, but the installation process hangs up at around 45% and I get an error message stating that there is 'corrupt content from a reliable source'. I have also tried a direct download, but end up getting another error message that it cannot locate the temp. file or something. I've tried downloading it for 32 bit as well, only to meet with the same problem. Any help would be greatly appreciated.
are you using the direct installer downloads located in this FAQ page? http://forums.adobe.com/message/3952360
unless you are running a 64-bit version of Firefox 4+, you'll only need to download and install the 32-bit version. do a full uninstall and try again.
