Premiere Elements 10 NVIDIA Video Card Driver Roll Back
If you are a Premiere Elements 10 user whose Windows computer uses a NVIDIA GeForce video card and you
are experiencing Premiere Elements 10 display and/or unexplained program behavior, then your first line of
troubleshooting needs to be rolling back the video card driver version instead of assuring that it is up to date.
Since October 2013 to the present, there have been a growing number of reports about display and unexplained
workflow glitches specific to the Premiere Elements 10 user whose Windows computer has a NVIDIA GeForce
video card. If this applies to you, then the “user to user” remedy is to roll back the NVIDIA GeForce video card driver
as far as is necessary to get rid of the problems. The typical driver roll back has gone back as far as March – July 2013
in order to get a working Premiere Elements 10. Neither NVIDIA nor Adobe has taken any corrective action in this
regard to date, and none is expected moving forward.
Since October 2013, the following thread has tried to keep up with the Premiere Elements 10 NVIDIA reports
