Windows – Can’t install Windows Media player 10, getting ‘a more recent version of windows media player is already running on your computer setup cannot continue’

I did a little digging, and there is an auto-generated play list of most recent items located in the following directory:

C:\Users\<username>\AppData\Local\Microsoft\Media Player\lastplayed.wpl

Using the command prompt and simply specifying this file fired up Windows Media Player and started up the playlist with a few songs that I had dragged to a playlist, but did not save.

You should be able to add a simple start menu/registry command that launches Windows Media Player targetting the file above.

I got this to work in Windows 7 with Windows Media Player 12, but there shouldn't be any issues updating the paths for XP and Windows Media Player 11 should have the same folder structure.

I haven't tried this but here is some documentation I found.

• Close WMP12
• Browse to %SystemDrive%\ProgramData\Microsoft\Windows\DRM and rename the folder to DRMbackup
• Open Internet Explorer as administrator (right click -> Run as Administrator) browse to http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp and click upgrade.
• Use data igloo to redirect the DRM folder -> thawspace.
• Authenticate the DRM'd files, reboot, and see if the authorization stays.
