This is where I got my impression that VCE could be used to compare Visio Diagrams: http://soft.postpdm.com/docs.html#Supported_image_formats

First, can you confirm that I can compare 2 visio diagrams on my computer using VCE? Assuming I can (because that is what I read), do I need any additional software (besides Visio) installed? I downloaded and installed VCE. I do not have a repository, nor really want to connect to one. All I want to do is compare 2 visio diagrams. Can I do this? And if so, how?
