On the Application Options window, I'm trying to change the default template's measurement units from Inches to Millimeters, but whenever I select mm, neither the "apply" or "ok" buttons respond, and the default template is not updated.
I'm still having this problem - I've read that UAC can sometimes cause similar problems, but disabling that didn't help, I've also disabled the firewall and reinstalled Inventor completely, but I'm still unable to edit the default template at all.
