I have a user that is on a Windows 7 64-bit machine and he has to different instances of excel open and coping information from one excel file to the other one. He can do it once and then when he tries to do it again excel says, "Microsoft cannot Copy and Paste."
I have tried to repair the install, that worked for a few days.
Tried uninstalling Office suite and then re-installing Office suite.
I reformatted the computer and did a fresh install of windows 7 and Office suite and today it started again.
I need to get a fix for this as soon as possible.
