Premiere Elements 11
What version of Premiere Elements are you using and on what computer operating system is it running?
Because of your user ID, I am assuming that you are using Premiere Elements 11 and trying to update it.
There are no Updates to 11 itself. There are updates for Camera Raw, but I suspect that the last offered via Help Menu/Updates will be Camera Raw 7.4.
Please see if your answer is in the following Adobe thread on the topic of the U41M1C212 error and updating of Premiere Elements 11.
Please let us know the outcome.
