You don't download the interop, you generate it. Have you seen this article?

https://learn.microsoft.com/en-us/dotnet/framework/interop/how-to-generate-interop-assemblies-from-t...

Also, it's "Interop.Acrobat.dll". I'm assuming that's a typo.

Hi Thom,  

Installed: Acrobat Version: 2021.005.20058

In CMD window, I ran tlbimp on the C:\Program Files (x86)\Acrobat\Acrobat DC\Acrobat\acrobat.tlb

I removed the solution's Interoop.Acrobat.dll and used this newly created dll.  Tthere are many Reference Errors - Not Recogzized:

using Acrobat;  

IJSMessageHandler

AcroPDDoc pdfDoc = new AcroPDDoc();

Where else on my system can I find the correct "tlb".  Is there an Adobe download link ?

tlbimp acrobat.tlb /out: Interop.Acrobat.dll

TlbImp : warning TI3019 : Interface 'CIConnectionPointContainerProxy' is marked as [dual], but does not derive from IDispatch. It will be converted as an IUnknown-derived interface.

Yes - Just Type in this post.  "Also, it's "Interop.Acrobat.dll". I'm assuming that's a typo"

Thx for help.

Hmm, that's a bummer. I think maybe you are going down the wrong path.

I would suggest a different route.

Have you tried the SDK C# samples?  Do they work correctly?

Have you tried to implement this using VB? Just as a test for the IAC functionality you want to use.
