Upgrade to PME 2020

As far as the problem with the images in Diagrams goes, there were security changes for PME 2020 that don't allow network paths to be used in Diagrams

Proposed Solution

When you configure a diagram in Vista to display an image and browse to that image, the path is saved in the dgm file as:


If the hyperlinks need to be updated, you can either try manually or Edit the file and make sure to identify a pattern that can easily be replaced in the files. 

Note: Always make a backup, try in a diagram, then extend to a couple of them, and when you are certain use any third-party tool to go through a bunch of files to replace.
–With notepad++ for example, but might be better tools on the web.
