Permanently disable "Edit PDF files with PDF Architect"

We have installed PDF Creator on a W2008 Terminal server (x64).

No matter what we try, we are unable to disable the option “Edit PDF files with PDF Architect” permanently. We have tried several options found on this forum, incl registry hacks, all to no avail. 
We want this option disabled for any user that logs on to this Terminal Server.
Is that possible?

Thanks in advance

have you tried not installing the Architect?
Which version of PDFCreator do you have installed?



Version is 1.5.1 which has Architect included?

Ik remove it an installed without the Architect option.
Missed that on the first installation.
