I installed the latest version of PDF Creator Plus 2.0 on Windows 8.1. I am having problems with profiles and creating new printers for those.
While logged in a local user who is a member of the Users group, I tried to create a new printer that corresponds to image printing in the PDF/X format. I had also created a custom profile for PDF/X.
I went to Application Settings and select Printers. I select Add Printer. I used the name “PDFCreator - PDF/X Image Format”. This prompts for escalation and I finish operation. There is no error message and the printer never appears.
It looks to me like I used an illegal character, so Windows OS refuses the operation with an error. But your application is failing to catch that error and notify me so I can try with a different name.
