DirectX 9.0c of course But since then, I reinstalled Windows 2000, pathed it (SP4 + updates - KB840987) Clean system, just MS Office, Acrobat Reader, SygateFirewall and antivirus. 1st run of SS31_MDCF.exe - "Can't download WindowsMedia codecs" All right, I put them to ...\Desktop\Downloads, run again ... no, the same. I installed WindowsMedia Player 9 (well I think this include WM codecs, I am wrong?) Run SS31_MDCF.exe again, and again... All right, I start internet connection, run again... and this time installer really downloaded WM9Codecs.exe Every else went great, but that's not the end of the story... After restatr SimpleBurner in tray, good. Click on SonicStage ... "Cannot locate needed files related to Windows Media Format. Exiting SonicStage." And it really exit..) I rerun by hand WM9Codecs.exe again and again. Runs smoothly, but no change. Restarted, no change. I found at microsoft MediaPlayer site some other WMCodec instaler, the same name WM9Codecs.exe but a little bigger file 1 416 944 This one goes smoothly, but at the end declares> "No entry point for GetUserGeoID in Kernel32.dll" So somehow, SonicStage is right - I don't have properly registered WindowsMedia Codecs. But how to register them correctly is my next question in my provate SonicStage adventure! But that's for tomorrow, it's middle of the night right here in Poland. By
