Acrobat SDK Loading Plugin Error (VS2022)

[Petej]

I am trying to get one of the sample plugins working on Windows 11 using Visual Studio 2022. The BasicPlugin compiles OK, but when I copy the dll into the Acrobat plugins folder, the plugin fails to load. I made no modifications to the code.

Any suggestions as to what the issue could be or where I can look to see what the problem is?

Cheers

32 bit or 64 bit version of Adobe Acrobat?

[Petej]

64 bit

[Bernd Alheit]

Is the plugin also a 64 bit version?

[Petej]

Yes it is.

Is it running with the new UI (hamburger menu top left versus File - Edit etc.)?

[Petej]

Yes it is using the newer menu style.

[Bernd Alheit]

You can disable the new UI.

[Test Screen Name]

The new UI is, I believe, still experimental and does not load plug-ins. (I believe that if someone has plug-ins ALREADY then they won't be offered the new UI on installing).

[Petej]

Right, that makes sense, thanks to both of you. I will disable it and try again.

[Petej]

I disabled the new UI. The menu item appears, but then about 2 seconds later, a message pops up stating that the plugin cannot be loaded and Acrobat closes. I have signed the plugin as well.

Ok...

1.is this a fully licensed Acrobat, showing editing functions etc, with an active subscription?

Or is it Acrobat running as Acrobat Reader?

The title bar should tell you (with the old UI).

2. Did you run Visual Studio on the same computer as Acrobat or did you move the file after building?

[Petej]

Adobe Acrobat Reader (64-bit) is in the title bar.

The file is on the same computer as VisualStudio, yes.

[Petej]

Could it be something to do with the RIKLA certificate?

[Test Screen Name]

Since it's the same computer, that simplifies the things to look for.

How and WHEN did you get the RIKLA certificate? (It would normally come near the end of the development process, not the beginning).

Also... it is expected that you will use Acrobat for development. Hence - you need to verify your plug-in loads in Acrobat first.

[Petej]

Apologies for not supplying more background information. This was a plugin developed several years ago, which stopped working and now I have been tasked to find and fix the problem. I downloaded the latest SDK, tried to get a sample working, but am stuck with the loading issue. The RIKLA certificate dates back to 2016.

[Test Screen Name]

Hmmm, I think new certificates may be required for the 64-bit version. I can't recall any details though.

[Bernd Alheit · Accepted solution]

Have you tested the plugin in Adobe Acrobat?

[Petej]

Will do that shortly, thanks.

Amber, !

[Petej]

Thanks, so I will try it in Acrobat Pro and when ready, request a new certificate for the 64-bit version of Reader.

[Petej]

All working now, it was down to my not using Acrobat and trying to do development directly in Reader.

Thanks all.
