Its possible that your old computer was 32bit, and the program worked on it.
Is your new computer 64 bit?
Since it has a Program Files (x86) folder, it looks like it is and the program may not be suitable on that hardware.
If you surf on this:
vbrun300.dll windows 7 64 bit
you'll find lots of articles on the problem you are experiencing.
Having said that, I'm surprised that the demo version works.
Is the exe for the demo in any of the folders you have shown us?
