I use the 1.1.60 version, but still get the message that wmdrmsdk.dll is missing. If I copy wmdrmsdk.dll and mfplat.dll to the windows folder manually it works fine. In DOSNET.INF I have [Directories] d5=\ [Files] d5,I386\wmdrmsdk.dll d5,I386\MFPLAT.dll In TXTSETUP.SIF I have [SourceDisksFiles] wmdrmsdk.dll = 100,,,,,,,2,0,0 mfplat.dll = 100,,,,,,,2,0,0 Seems right, but still dosnt work unless I manually copy the 2 files to the systemroot folder.
