When trying to copy text from a PDF document in Adobe Reader you may see the following error message
“There was an error copying to the clipboard. An internal error occurred”
Although this issue appears to have been around for some time I have now seen it a number of times on Windows 8 machines running Adobe Reader 10 and 11 (including my own system).
If you search the web there are many postings on this one offering various ‘fixes and workarounds’.
However, what I have discovered is that the actual copy process does complete even though you get the error.
All you need to do is ignore the message and paste the copied text in as normal.
This has been the solution/workaround on three systems running Windows 8 so give it a try.
Note: Curiously on my system only one user account gave this error message. I had two user accounts, both set as administrator, and one copied fine but the other copied but gave the error message.
