Customer had installed a new workstation with a Single User software protection key plugged in the back. Networking was disabled. On startup Citect reported a software protection failure.  

The user had copied a citect.ini file from another workstation and modified it to suit the new machine. As it turns out it had a spurious entry in the Citect.ini file [CLIENT]Manager=1 which caused Citect to look for a manager license which was not encoded on the key.

Setting the parameter to [CLIENT]Manager=0 corrected the problem.

It is actually quite important for a healthy citect system that the Citect.ini file only contains entries that are appropriate to the running system. Spurious entries can cause all sorts of difficult to diagnose errors.
