No specific info about version 7.1. Please visit the main page of Nuance PDF Viewer Plus on Software Informer.
This program is not very useful. The regularly used extensions, it converts very easily. The little-known extensions, (which is why I downloaded it in the first place), PDF Viewer is not performing as advertised.
Love it! I can do anything to a PDF. Often times I need to redact information or add a text box on the document. The porgram is very user-friendly!
