I installed gsview and gs and tried it. AFAIK, gs didn't seen to complain. I also tried GIMP. While it didn't complain, the picture displayed is horribly bad.
An "invalidrestore" error signals an improper restore.
E.g., a string, dictionary, or procedure is left on the
stack that needs to be discarded before restore.
Probably a dictionary with no 'end'.
Two obvious possibilities:
- there is an invalid restore. This should be fixed.
- something is wrong with the Word interpreter (quite
possible given its history, but perhaps surprising
for this particular problem)
Does GhostScript report the same error?
