Unable to instantiate ISWiAuto25.ISWiProject

I'm using InstallShield 2019 R3 standalone build.  I added ISWiAuto25 as a reference to a VB .Net project.  I'm using Visual Studio 2012 for legacy reasons. I could easily switch to VS 2019 if it will help.

Dim oIPWI As New ISWiAuto25.ISWiProject

When I execute the previous line I get the message:

"Retrieving the COM class factory for component with CLSID {23D7FBC5-7429-41A4-8318-3D0ECA563C8} failed due to the following error: 80040154".  

What do I have to do to resolve this error?

Thanks in Advance,

Hi @cbsoth ,


Did you give a try of manually registering the ISWIAutomation25.dll,having cmd to be launched as Administrator?
