WMP - First time use

[Bati9]

Is there a reliable way of figuring out if WMP has been initialized on
a user's machine? I just found a bug on my app written in C# and using
the WMPLib::WindowsMediaPlayer class - it crashes when I try to import
the artists from a WMP app that hasn't been run yet.

I know on XP, there's this reg key that i might be able to use:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\Preferences]
"AcceptedEULA"=dword:00000001
"FirstTime"=dword:00000001

But this doesn't seem to be the case on Win7.

Define crash.

Are you app and WMP both Win32 or both Win64 apps?
