We are investigating currently this problem. I will contact you on your e-mail for more details.
We have installed Autocad 2015, Inventor 2015 and PDF Creator on our machines.
Similar Problem here, printing to PDF in any application starts Inventor Installer dialogue...
Dear Daniela,
I've a same problem as brian.crabtree. Could you help me please with this problem? Unfortunately isn't some resolving in this topic. Thank you very much.
Ondrej
I have sent separately to Ondrej a file which should register his Inventor installation and hopefully will solve the issue for him.
I applied a fix to this original issue, but it seems to now invoke a Navisworks installer whenever PDF Creator is launched in another application.
