I'm getting the same error as the OP in this thread. I'm following the instructions there and in this thread.
I'm down to the point where i boot into Safe Mode and run com_fix.bat as administrator (have also tried running CMD as administrator and running com_fix.bat from there.).
I get the same error (see below) as mcclaigg in his posts near the end of the second thread mentioned above but his fix (running the Ghost install from the cd as administrator) isn't working for me.
The reason i'm posting in the first place is because i get the following error when performing the instructions you linked, whether in normal mode or Safe Mode. I only tried Safe Mode because mcclaigg said they had success with that as a solution to this error.
I can't click to link in your first thread so I can't see the original error that caused all of this. Can you tell me that, and also let us know if this ever worked? If so, what happened at the time it stopped working?
