We have QTP for GUI test automation which is based on VBScript.
I decided to use VAPI VBScripts as a wrapper to run our internal legacy scripts for Unix environment written in TCL from Quality Center.

Since both types of scripts use VBScript, my idea is to run and edit both of them from QTP.

When I just copied and pasted a debugged VAPI VBScript in QTP and ran it from Quality Center, I got the error: Class not found.

What do we need to add to a VAPI VBScript to run it from QTP?
