How to fix the runtime error "-2147220992 (80040200)" while opening Mathcad file using excel vba code?

Question

I'm trying to open a MathCAD application using excel VB code. But I'm getting a runtime error "-2147220992 (80040200)". I have an indication as Automation error. Add your comments to solve this.

Dim eWS As Mathcad.Worksheet

Set eApp = CreateObject("Mathcad.Application")
eApp.Visible = True
Path = "C:\Desktop\Test.xmcd"
Set eWS = eApp.Worksheets.Open(Path)
