Hi everyone. Hope someone can help me with this rather annoying problem I have. I have used the WMP11 Integrator to slipstream media player 11 into my Windows XP Professional Corporate (x86) install share. Using the unattend.txt switch to perform a network install, I get a message saying that wmdrmsdk.dll is missing. If I skip the file, mfplat.dll is also missing. The temp directory that Windows creates on the local drive does not contain those two files, but the network i386 folder does. If I create an install CD and use a Winnt.sif instead, it works just fine. Since I first had this problem, SP3 has been released so I tried a fresh i386 slipstreamed with SP3 and WMP11, but still the same result. I have tried putting the file in the $OEM$\$$ too with the same result. Annoyingly, I have had this working, but not sure what has happened. Does anyone know what it might be?
