There was an error while copying to Clipboard. An internal error occurred.

After reading all the suggestions, I have tried the solution to untick Enable Protected Mode At Startup. I have version 10.1.16 and this worked for me. The box has moved and is in Preferences / General but works a treat. Thanks to all for your help to solve this problem.

Had this issue for about a month now.. just showed up out of nowhere and pretty much happens on all of my copies from a .pdf now.

At first I tried this: windows 7 - How can I hide the error message "There was an error while copying to the Clipboard. An internal error occur…

It kind of worked, but it eventually came back.

I just uninstalled and re-installed Acrobat .. for some reaosn my Acrobat installation was over 10GB... after re-installing it's back at 2.16 (pro version) which is where it should be.

So far I'm not getting the error anymore.

Interesting to see that this error is more than 6 years old!

I recently stumbled upon this error myself and don't have a solution in that I know how to prevent the error from occuring, but I use an Autohotkey script that closes a couple of other  irritating dialog screens e.g in Lotus Notes and SAP and have added this dialog screen to my list, so it automaticly closes the obnoxious dialog screen with the error. I don't suppose you are interested in the entire script as it is quite specific to my needs, so I have made a very simple program that you can run, will sit in your System Tray and will watch for the Dialog Box and closes it down immediately. You can download it from my website free of charge, together with the source code.: http://www.zwagers.eu/henkjan/Software/HJMSoftware.htm (PS: to end the program from running just press CTRL-Pause/Break).

Good luck and best regards.

Did you try disabling all add-ins in Adobe Reader?

I only signed up to say that 6 years in the problem still exists. Way to go guys! I have Adobe Reader XI (most recent version, i.e., 11.0.11) unter Win7x64. None of the fixes suggested here helped:

- I do not have Skype Click2Call installed.

- There is no Babylon plugin or whatever on my computer.

- I cannot untick "Enable Protected Mode at startup", in fact this box is unticked for me and it is disabled (gray) so I couldn't tick it either.

It is beyond my understanding how such a bug can persist so many versions and it is never taken care of. Especially given the fact that the message could simply be deactivated since the copy-paste does work despite the annoying box. Also, this does not happen in Adobe Professional. Is the strategy here to annoy people in order to switch to Pro?

I have this error when I highlight text and click "create a bookmark". Its completely annoying. I have to literally keep clicking "create bookmark" until it eventually decides to make one.

I'm using Adobe Acrobat Pro XI

I was happy to see paulh solution to getting rid of this annoying *feature*, but alas it does not solve the problem for me.  I may not see it as often, but the problem still persist.  I am using Reader XI v11.0.07.  You think someone at Adobe would have enough brains to fix this problem by now after all these years.

The error message no longer appears with Reader 11.0.5 in our environment, but as far as copying out information, I have gotten used to saving the PDF as a text file first and doing all Copy/Paste operations that way. Might not be the best solution but it works for me.

Hello,

I'm having the same problem with Acrobat Reader X 10.1.4. I'm not using anything related to Skype, not even Internet Explorer, so this should not be the problem.

However, I'd like to inform you about something I think could be relevant for developpers: I'm experiencing a similar problem with Microsoft Office 2010, at least with MS Excel. This is, when I cut-paste or copy-paste cells, if I do it by dragging the cells, I often get the message "Couldn't empty the clipboard. Another program could be using the clipboard" (or something like that, free translation from Spanish), a very similar message to Adobe Reader's. However, if I cut-paste or copy paste using the menu or throughout the Ctrl key, there is no message. In both cases, the cells are perfectly cut/copied and pasted, just like the message in Adobe Reader doesn't avoid the copy to be done.

The interesting thing is that Office has a clipboard manager, and when I drag the cells and get the "Couldn't empty clipboard" message, I can see that the clipboard is actually empty.

I know this is an Adobe forum and MS Office problems are probably irrelevant to you, but my goal is to provide you some information for solving this Reader problem, which is surprisingly not solved yet.

Thanks for your help

Dear Adobe Developers,

This issue has been going on for 3 years.

I have just received this error for the 1,000th time.

You have just achieved something which is extraordinary: you've goaded a normally mild natured user into extreme anger.

Thus, I'm accusing the entire Adobe development team for Adobe Reader of being a brain dead bunch of morons. And don't claim you don't deserve this label, because you do.

Yours sincerely,

A Normally Mild Mannered User
