After installing MC13, as I used to have MC12 before purchasing the update, I have the interesting situation where MC13 wants administrative access to run.
If I open MC13 my just starting it on the desktop, and drag a song on to it, then it plays great, and is happy. Where I am running into the issue is if I just double click on a song in my collection, not drag it to the player, or if the player isn't open to start with, I get the message it needs an Administrative login. If I don't give it the Administrator login, and password (which is a bad idea in my book, stuff should not need to run as admin) then it fails and gives me the message "Unable to register controls. Please run as a power user".
Now my environment is that I am running on my desktop on a Vista Ultimate x64 machine, but it's part of an Active Directory/Domain, so I don't really have a Power User setting, that's not so much part of AD. I never had this issue with MC12, but now after installing the update to MC13 I do, any ideas how to fix this one??
