Guide To Error 80040155 In Windows Media Player
The error "Interface not Registered" while burning a CD should be fixable by
simply reinstalling WMP over itself. (If you get this while trying to move
content to another portable device reinstall the drivers for it, and then
follow the rest of this post.)
Depending on how WMP was installed on your machine you may already have the
installer. If you do it is located in C:\Program Files\Windows Media
Player\Installer. The file name of the installer is "mpsetupxp.exe"
If you don't see the folder then run C:\Program Files\Windows Media
Player\setup_wm.exe and that will re-download the installer and install it.
