I have some VBA code that runs in a worksheet when a button is clicked. The code runs perfectly on some computers, but on others nothing happens when the button is clicked. I've checked the macro permissions and they are the same on all of the computers. I'm also aware of the issue with the Windows update that came out in December 2014. I've run the Fix It to no avail. http://support.microsoft.com/kb/3025036/EN-US
Is there a setting outside of the Trust Center settings that could be causing the issue? Is the Microsoft Fix It incomplete in some way so that it's not working on some computers?
