Problem:
Win2PDF stops working after Winfax, FaxTalk, or RightFax is installed.

Solution:
WinFax 4.5 takes over the FILE: printer port, thereby preventing any other printer from printing to a file. This interferes with Win2PDF. Upgrading to WinFax Messenger Pro 6.02 will solve the problem.

 

Uninstalling the fax software will also resolve the problem.
