Running 32 bit apps on Windows7 or Vista 64 bit

[JD George]

The long and short of it,
We paid to have a program built as an add in to SolidWorks. I believe it was written with VB6 and now does not work on the newer 64 bit OS. Now the programmer wants an exorbinant (sp?) amount of money to update to work with the 64 bit. Is he legit or just trying to make more cash?

Please help me out as my understanding of this is nill.

Thanks,
JD

Hard to tell without seeing what it does.

Do you have the source code for the VB6 version?
