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

I was having this problem on Acrobat X and I tried everything in this thread and nothing worked and now I finally tried this:

Help Menu -> "Repair Adobe Reader Installation"

And BOOM it's all fixed!!!!!  No more stupid copy error!!!!  

Wow still no answer. $450 for pro and you cant even fix an error spash screen. Copy and Paste are basic function of any program. This has been going on all the way back to 2008

And you wonder why people hack your crap a$$ software

None of the above solutions have worked for me. To be specific, here's what I've tried:

• Uncheck "Enable Enhanced Security"
• Apply full permissions and ownership to ...\Roaming\Adobe
• Manual creation of registry key based on this page: Protected Mode — Acrobat Application Security Guide
• Uninstall/reinstall
• No Skype add-ins, so not a solution
• Problem exists with/without using Microsoft apps
• PDF Copy-paster.exe from a deep forum search - has no effect other than removing hard returns, but error window still shows up.

Win7 x64

Acrobat Pro 10.1.16

Any more suggestions?

I hate it when they say "We couldn't replicate it" or "what is the version of your windows,..."

I have been using acrobat for so many years and it has always suffered from this issue. It does not happen on all files. It depends on the file and probably if the text is distributed in a weird way (like there are hidden alignment and formatting characters in the text).

Anyways, by now, adobe should have figured a way to solve it or at least look at their code. That window pops up from somewhere. Just add an option to disable it.

It's like they have a window written in the code and they are ignoring its existence.

Used this solution and it worked for me

Edit --> Preferences --> Security (Enhanced) --> Uncheck "Enable protected mode at startup" (or "Enable enhanced security).

Same here!  Have had this issue for longer than a year through different versions of Adobe Reader on my laptop with Windows 7 and a clean install of Windows 8, then 8.1, also on Terminal Services servers (Server 2008 R2, Server 2012), you are useless Adobe!!!!  COPY AND PASTE, how hard can it be?!!!???

Here's a solution though, uninstall Adobe Reader and install Fox IT reader - http://www.foxitsoftware.com/Secure_PDF_Reader/

Wonder if Adobe will delete my post...

I can't believe a program as mature and expensive as Acrobat Pro can't copy and paste. Unbelievable.

Where are you Adobe? This issue has persisted for years!

We seem to have managed to get around the problem by switching off the Office Clipboard (or closing all Office programs):

https://office.microsoft.com/en-gb/help/turn-off-the-office-clipboard-HP001018257.aspx

Maybe it's something interfering with the clipboard that causes the issue, although there must be more involved, as only one of our users has had the problem and they all have the Office Clipboard working and use Adobe Reader.

I'm wondering if this problem is common for some people, but strangely absent for others, because it's some conflict between Acrobat and any 3rd party program that intercepts the clipboard. For example I have the PureText+ app that catches copied text, and allows you to paste it without formatting using [Windows Key]+V.

I also have VNC, a remote desktop app, that will allow copy and paste of text and files from one computer to another.

Many programs out there intercept the clipboard to do their own special handling of copied text, images, etc.

However, in my experience, the text is always copied anyway and pastes fine.

If they simply remove the useless error dialogue, I would consider the problem 100% fixed.

Now if they could just fix the photoshop clipboard error where doing ctrl+N sometimes results in your new document being correctly sized to a copied image, and sometimes results in the size of the *previous* copied image. That one's been around a decade.

I think Microsoft Visual C++ 2005 Redistributable might be responsible for this error. I'm using dictionary which requires MVC++ installed and I got error message only when the dictionary is running in the background. I hope this hint will help to resolve this issue.
