I have removed both updates, KB958437 and KB967699, and applied the Hotfix provided by Microsoft. This fixed my problem of not being able to copy and paste data from Excel into Access.
On 6/22, three updates came through and I started immediately receiving this error again. I looked at the descriptions and only Service Pack 2 had anything to do with Access and/or Excel. Could this be my problem or is it one of the other updates?
