Sounds like your IT staff install NovaPDF when you need the AdagioPDF (a licensed OEM version of NovaPDF). AdagioPDF should have been installed when you did the Adagio workstation setup (assuming you did this correctly and you had the appropriate rights for the install to completed.

My suggestion is to uninstall Adagio and NovaPDF from the workstation and then redo the Adagio workstation setup with the correct user permissions (grant the user administrator status).
