Okay thanks, that helped with enabling the Micro-Player in the toolbar.
But it's somewhat strange, that the installer although having admin rights wasn't able to register the dll.
Vista isn't Admin/no Admin, black and white, like other Windows OSes. Either way it's restrictive when it comes to system access, so if it doesn't reg the .dll properly, it's probably down to errors with the install script. Though I don't get it myself, with x64 Vista...
Maybe issues with the dll allready being registered somewhere else?

I did a filesearch over all drives and there was only one "deskplayer.dll" - the one in the MediaMonkey folder. So there shouln't be any other software using it. And what I didn't mention so far: my Vista installation is still "clean". I installed Vista, downloaded all Windows updates and installed only the most important software - no deinstallations so far.

Believe it or not, I'm extremely happy so far. For me it's the best Microsoft OS ever (and I'm using MS operating systems since MS-DOS 3.3 days).
Before installing the recent version of MediaMonkey 3.0.1.1127, I thought it would be a good idea to do an uninstall of the older version first.
One file couldn't be deleted: DeskPlayer.dll. I had no chance to remove this file afterwards. I activated the hidden administrator account, set myself as owner, ...
The only chance I saw was to boot with Acronis DiskDirector and delete the file from there. This worked, but Vista refused to start properly afterwards!
So I did a completely fresh install of Vista (and made some disk images while installing new software).
I learned, that it's possible to install MediaMonkey 3 as long as I don't install NOD32 3.0 and Outpost Firewall Pro 2008. Disabling both doesn't make any difference, I always get the DeskPlayer.dll error message.
Possible solution: MediaMonkey can be installed and uninstalled in safe mode.
