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.

For Reader, yes. For Acrobat, you can continue to use SDK 7 if you wish.

I have build my plugin with acrobat 8 SDK by VS2005.

And then run makemd32.exe return by adobe as the following steps:

  • Type the path to the plug-in.
  • Type the path to the keypair file generated above.
  • Type the path of the file to store the encrypted message digest. It is recommended that you save this as msgdig.rc.

Next i replaced my plugin's  API_ENCRYPTED_DIGEST data segment by msgdig.rc.

Build my plugin.

Startup Adobe Reader 8,the same error appeared.

Also,the cert returned by adobe is 624 bytes and i noticed that it should be 554 bytes said by "Developing Plug-ins and Applications" in acrobat 8.1 SDK,

Is it OK?

For Reader 9 I see the helper below pointed by adobe.

http://livedocs.adobe.com/acrobat_sdk/9/Acrobat9_HTMLHelp/wwhelp/wwhimpl/js/html/wwhelp.htm?&accessi...

As the doc mentioned,after I receive my cert i just need using SignPlugin.exe to sign my plugin,but that cause the "Plugin Hash Failed" error.

If i copy the dummy.rc & RIKLA-DigCert.rc content into my plugin's resource file,the signing process is successful.

But it can not load by reader 9.

Did i missing some keys?

That is correct, because the key you were provided is only for Reader 9. As described in the agreement that you signed to obtain the key, the key is only good for a single version of Reader.

But the agreement said that

“Reader” means versions 8 and 9 of the Adobe Reader software application, on any platform, if made generally  commercially available by Adobe during the Term.

Even if the key is only for Reader 9, i signed my plug in conformed the way Adobe mailed me and it still can not be loaded.

OK - then you have a agreement for both. I haven't read them recently. It should then work.

I would contact support and check in with them...

Excuse me. I don't know if my case is the same as the rest of people, but maybe It can be usefull to tell you. Two days after the mentioned error message appeared I was thinking a little about what I did on my PC just before the error began to manifest. I realized I just installed Babylon software (the trial version). Then I uninstalled it and all is right again. Good luck

Last night I installed Babylon 8.0, Feedburner  and Wordfst and after these actions I couldn't open my Adobe Reader 9.3.3 which functioned fine before these installations. I went to C:\Program Files\Adobe\Reader 9.0\plug_ins and find that the main culprit for this was Babylon 8.0. Then I tried to remove it but every time I opened Babylon this folder recreated itself. I probably should have deleted it completely, i mean the whole program but I really need it so now I use one at the time and every time I have to move Babylon plug in to folder Optional or to delete it. It works only if Babylon is closed. Only then my Adobe Reader works. I have to say its really tiresome...

It is very useful your info. I have not tried again. I have

uninstalled Babylon like you. I will not installed it until Babylon

repair this bug. I think that is the better to do.

Thank you

I too downloaded Babylon translator. right after that I got the "invalid plugin detected" error message.  I didn't put the 2 together until I read this thread. Last night I uninstalled Babylon translator, and so far I have been able to view pdf files and  I have not got the error message anymore. Keeping fingers crossed that it's fixed.

Yes it works sure. However, It would be better achieve that both

programs (Babylon and Acrobat reader) works well when both were

installed in your PC. I don't know what to do. I have written to Babylon

people but I have not any answer yet.

I hope some patch correct soon this problem. Good luck
