This is an older version of PaperPort, 7.0.
The odd thing is that it installed OK in Vista RC1.
Do you think your edit will work on this?
No, that edit will only work on installers that just say that you haven't
got the right version of Windows, and says that it will only work on
NT/2000/XP/2003.
Assuming you are not trying to install that on Vista64, it looks like the
virtual DOS machine for running 16-bit apps have been changed since RC1, and
made less compatible. I'm surprised it worked before, as NTVDM is not
supposed to be able to access hardware directly.
You should really look out for a newer version of that program if you can.
If it worked before in RC1, you could try replacing NTVDM.exe with the older
version, under Safe Mode, but it may cause instability.
