What exactly means "cannot"?
Pat I am running windows 7. The Adobe Flash version is 11.7.700.169. About a month ago most of the videos I get from people via email or the ones I get from the internet do not play. By that I mean I can hear the audio but I see no video. I can view some UTube videos ok but not all.I have downloaded the latest version of Adobe Flash twice but that did not help. I am making the assumption that Adobe Flash was installed becasue after the download was complete there was no indication that an installation had taken place. I wonder if this problem is a common one. Other than using System Restore I really don't know what else to try.
