InDesign scripting: System.Reflection.TargetException: 'RFLCT.Targ_ITargMismatch'

[ArtisticMagic]

Hi,

I'm getting a "System.Reflection.TargetException: 'RFLCT.Targ_ITargMismatch'" error when trying to run a simple scripting program from Visual Basic. See the attachment.

I wasn't getting this error when I ran similar scripts a few years back. What do I need to do?

Visual Studio 2019  Visual Basic

InDesign 2020

Not sure about VB errors, but can you check that the active document has been saved successfully and actually has a name? That's where I'd start.

Brian, thanks! I just found out that it was an InDesign installation problem.

I just reinstalled InDesign from scratch, ran it once as an administrator, and the problem went away.
