I get an Automation error after I add the ChemDraw for Excel Add-In.

First, remove any of our Add-Ins from Excel. Quit Excel and launch Excel to confirm that the Automation error is gone. Make sure that after removing our Add-Ins, there are no lingering ChemDraw, ChemFinder, or ChemOffice menus or toolbars present in Excel. If there are, remove them. Now add the ChemDraw for Excel Add-In back and retest. If the problem still occurs, remove our Add-Ins again and, uninstall our software using the Add-Remove Programs control panel, then reinstall and retest. If the problem still occurs, there may be a problem with your user account. Try creating a new Windows user account. Login into Windows with the new user account, install our software and retest.
