Extract the registry file to any directory you choose.  Then, 
double-click on it to merge it with your own registry.

Go to start and click on Run.  Type "regedit" in the commandline and 
hit Enter to bring up Regedit.  This works like Windows Explorer.

Look in HKEY_LOCAL_MACHINE\SOFTWARE\Mpath\Mplayer\Manifest\Game285

This contains the registry info for the AvP enabler.  All you need to
do now is change any directories or command lines you see so that they
suit your installation.

All I have done here is exported my own registry enabler, so I cannot 
guarantee this works.  Don't blame me if anything screws up.  If you 
have anything to say, please contact me.
