Sorry for the delay on picking this up. I like the idea, but disagree with the specific instructions. There is no need to copy the Runtime to the same folder as the qvw. That could be a bad practice as you can wind up with multiple copies of the Runtime. I think it's better to keep one copy.

Also, I think it's important to have people CALL Qvc.Cleanup.

How about:
Quickstart:

1. Unzip the distribution
2. Add $(Include=path to unzipped folder\qvc_runtime\qvc.qvs);
   at the top of the QlikView load script.
3. Call Qvc.* routines as required.
4. At the end of your script, CALL Qvc.Cleanup.
