I have the same problems.

First off, I'm using WMP 10 on XP (SP3) inside a VMWare virtual machine.

I have individualised the system, getting me the following text in the text box next to the "Multi Scan" button in drmdbg.

I know it's not v11.0.6000.7000 but that's what I get from individualising, DRM media plays fine in WMP and I don't know how to get a different version (I have no "DRM\cache" directory, no "Indiv01.key" etc and I do have both hidden and system files visible)



I get the ReadProcessMemory_error and WriteProcessMemory_error on every version of drmdbg I try and no DRM2 directory or key file appears. I would guess that it can't debug the wmp process so it can't extract the key file, since the name implies it is a debugger similar to ollydbg and wanting to read a process' memory confirms this.


I've tried every suggestion here, including deleting the DRM directory contents.


I also tried FairUse4WM on a DRM protected file that does play fine in WMP10 but FairUse4WM tells me:
A different version of FairUse4WM could get my keys ("2 keys found") as soon as it started without me selecting anything. However, when I tried to run the DRM protected WMV through it I get:Even though (as I have said) it plays fine in WMP10 and is definitely protected (VLC plays garbage when it tries, my network activity shows a licence fetch by WMP and WMP even says when it is downloading the licence).

Edit: Fixed that last problem using the following forum thread
FairUse4WM Error: filename.wmv does not appear to be licensed to you
