I had upgraded to Windows Vista 64bit system. I had updated everything after the upgrade. The default web browser which I can using in Internet Explorer. Now when I try to play some videos it is not working. It is asking for flash update but that does not looks to be working well. I tried many things here but nothing worked out. Can anyone simply help me how can I simply install flash here. I am having the setup file of flash and it is installed. There is no error also.
