Invalid plugin detected adobe reader will quit что делать
I have gotten the RIKLA from Adobe. And I use the example code BasicPlugin(you can download it from Adobe wetsite) as my plug_in, then, I made the api file according to the steps in document in the «Creating an Adobe Reader Plug_in» section of the «Developping Plug_ins and Applications». As last,I copy the api file to plug_ins folder, open Adobe Reader 8. I saw under the Tool memu there is a new menu named Acrobat sdk so that I think the api file is loaded successfully by Acrobat reader. But an error appears, it is «invalid plugin detected. Adobe Reader will quit». Can someone tell me why?Thank you.

The first thing to check is whether the plug-in actually does its job
when you load it in Acrobat.

When I open the acrobat reader, I must click tool menu, otherwise the error will appear and the reader has no any response. But if I click the tool menu, the error does not appear. At this time, I can test the plug_in, it works. But as long as I leave the tool menu, the error will appear.

When I open the acrobat reader
I assume you mean Adobe Reader; the last version called Acrobat Reader
was 5.1.
What I was asking you was to check that the plug-in loaded correctly
in Acrobat. NOT in the free Reader. You must test in Acrobat first.
I assume you have got a Reader enabling kit and license from Adobe to
write Reader plug-ins? If this doesn’t sound right, you need to read
the document about developing for Reader.

Even I tried the BasicPlugin Sample but I did not get the Menu added in the menu bar. Every time, I open my reader I get the error «Invalid Plug-in». Can you please tell me what the issue is? Because you are also getting the same error but at least when you click on tools options, you can see your plug-in. I am not even able to see the plug-in.

Thank you!
I tried up-issues (Adobe Reader 8.1.2+) and got the same error
«invalid plugin detected. Adobe Reader will quit».
I fixed this error by following laborious steps described in the Adobe
Technical Support Home.
Not sure if this helps you guys; but worth a try. Developers should
say if this the real cause.
You can find these in the «plug-ins» folder. [C:\Program Files\Adobe
\Reader 9.0\Reader\plug_ins]
«HAEvents32.api» is the main culprit. Along that, I removed
«Helmant32.api» and «Helmbkmk32.api».
Without deleting these two, an error or two might come but still PDF
will work. I tried all these combinations.
Note: Delete these files if present anywhere else in the system else
they recreate themselves.
Forgive me if this is not a place for kids like me. 🙂 I am not a
Techie 😉 Thanks every one.

Those are NOT standard Adobe plugins. I would contact the author/publisher.

How to resolve Adobe Acrobat Reader DC will quit error message?
If you encounter an error saying «Invalid Plugin detected. Adobe Acrobat Reader DC will quit» or «Invalid plugin detected. Adobe Reader DC will quit» or when using the Adobe Acrobat Reader, don’t worry. It appears that one of the DDL files: «ComposerPlayerControl.dll» causes this issue. To stop this error message remove this dll file.
- Go to C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\plug_ins
- And then remove «ComposerPlayerControl.dll».
- You should now be able to open PDF files without issue.
Alternative solution
If this doesn’t work then there is an alternative solution. The issue could also be related to the fact that you also have a Babylon translation tool installed.
In computer systems with the Babylon translation tool installed, Adobe Reader 8.1 often quits due to an invalid plugin error. Re-installing Adobe Reader will not fix the problem. The solution is simple, you need to uninstall one of these programs.
If you need to use the Adobe Reader, temporarily uninstall the Babylon software and reinstall it when you will no longer need the Adobe Reader. Or try to find an online alternative for Babylon, such as Deepl or Google Translate.
