Error 457 - This key is already associated with an element of this collection

Windows 7 x64
PDFForge PDFCreator 1.7

When printing from any application to PDFCreator printer the above-mentioned error is displayed. Clicking the button to “Exit Procedure” will bypass and printing will complete however the issue is persistent.

This was asked in a previous thread back in 2013 but no answer was ever provided.

I will be happy to provide logs if requested.

James Stockton
