Bug in PDF Creator 2.2.2? Requested registry access is not allowed

After upgrading PDF creator to version 2.2.2 we receive the following error (only relevant info):


… Requested registry access is not allowed … 
at pdfforge.PDFCreator.Core.Printer.PrinterPortReader.ReadPrinterPort(String portName) …

I used procmon to catch the error and got an ACCESS DENIED error on the following regkey: 

HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors\pdfcmon\Ports\pdfcmon

I resolved the issue by giving everyone permission to read the key but I’m looking for a better fix. My questions are: 
  • is this a bug in this version? 
  • Do others have the same issue?
  • Is there a better way to fix this? 
  • System and Administrators have read access. Why isn’t that enough?
