Help, WMP11 and .wmv issues Hello all, I have Vista Ultimate SP1 64bit first of all installed. I have Windows Media Player 11. I have been able to use it just fine for quite a while. However only recently I can no longer play .wmv files. They all come up with an error stating "cannot access the file... the file might be in use.. blah blah" I have tried EVERYTHING! I have searched everywhere but here. I have installed every codec in the book and then uninstalled them. The funny thing is I have a Zune and my Zune software will play .wmv just fine. Any suggestions or anyone have this issue and solved it? Help!!
Try this: Start -> Programs -> 'Right-Click' on Windows Media Player -> Properties -> Advanced -> enable 'Run with different credentials'. or you can start up Windows Media Player: Tools -> Options -> Performance -> Advanced and check off 'User Overlays' under Video Acceleration. Good LucK!
