Error 430 when integrating VBA/Excel with Prime - "Class does not support Automation"
I'm using Excel and Mathcad files that were perfectly functional on another machine. When I try to run them on my current laptop, I get "Run-time error '430': Class does not support Automation or does not support expected interface"
The problematic code is:
Dim Mathcad As Ptc_MathcadPrime_Automation.Application
Set Mathcad = New Ptc_MathcadPrime_Automation.Application
I'm using Mathcad Prime 4.0, Excel 365, and Windows 7. Has anyone run into this error before?
