Has anyone used Primopdf? I've just downloaded it, but just started to try and run it, and got a warning message:
"The publisher could not be verified. Are you sure you want to run this software ... This file does not have a valid digital signature that verifies its publisher. You should only run software from publishers that you trust".
Should I trust it - any advice would be very welcome. I want to use it for a newsletter created in Publisher 2002, to be able to circulate it by email.
