Although I maintain my own support forums at
Shark's Forum I feel that going out on a limb to assist a new user use my codec releases is somewhat invigorating especially since this thread begins with the usual statements I see
posted from the uninformed,
(nested quote not copied, basically says codec packs are a bad idea)
If you had bothered to read
Shark007.net - x64 Components addon you would have seen as almost the 1st line posted, in bold text, The x64 Components
addon requires the 32bit release to be installed as a prerequisite. That directive is in bold text for a reason . . .
hevnbnd, remove the tech preview because it isnt doing a damn thing for you. Install my 32bit release for the OS you use (please do your best to cleanup your current 32bit mess 1st), and sit back and watch some video's in x64 Media Center.
Also remember, on x64 systems, my releases will install '2' Settings Applications. 32bit and 64bit codecs each have thier own settings. (mostly) The user needs to know the target OS of the player which they wish to adjust and select the proper Settings interface for that player.
example, a default x64 installtion uses the 32bit WMP as default and MediaCenter is x64 only. So to make an adjustment to WMP you would use the 32bit Settings Application and for Media Center you would make the adjustments in the x64 Settings Application.
