Make sure you are using the horm.dat file extracted from the XPeSP2FeaturePack2007.iso found here http://www.microsoft.com/downloads/d...displaylang=en
I'm pretty sure you've already seen it but follow the directions found here http://granturing.blogspot.com/
Ohh your in luck here are the extracted files I'm using Ewf-Horm files.zip
Hmmm just had a thought if you already have EWF up and running and attempting to copy the horm.dat file to the root of C: while EWF is enabled the change would not be saved when you reboot as EWF was enabled.
Just in case make sure you disable EWF by running "ewfmgr c: -commitanddisable –live" then copy the horm.dat to the root of C:
Renable EWF with the "ewfmgr c: -enable" command then reboot check and make sure the horm.dat is in the root of C: after the reboot, hibernate then restart hopefully horm should be working for you
I suggest you make two .bat files one to disable EWF and the other to Enable EWF they come in handy when making changes.
