We have users running both XP and 2000 without administrator privileges.
When we were using PDF Converter 2.10 we had an administrator install the printer using install.exe on the user's machines. The install.ini file did not have the licensee or license code. The application called DriverInit and EnablePrinter. Everything worked fine.
We upgraded to version 2.51-b and followed the same installation steps. Now the users get the -41 error code. I had an adminsitrator re-install the driver with the licensee and liceense code in the install.ini file. Then it worked correctly.
Is this a new requirement for version 2.51-b?
