COM Add-ins: Chemistry Add-in for Word installation issues
I installed and later uninstalled Chemistry Add-in for Word. I realized I wanted it back and tried to re-install. It appears to be installed correctly, but the "Chemistry" tab no longer appears on the ribbon. And when I right-click on a chemical
name, then open the "mark as chemistry" submenu, it has an empty option that does not do anything when I select it. I may have messed with the "COM add-ins" settings when I was trying to uninstall.
Also, I have reinstalled both Microsoft Office and the Add-in, but to no avail! Please help!
