I was opening Inventor files from Vault with two Inventor instances running. The message we get is this (and the file will not open):
Since there is already a prompt in place, it would make it easier to have a selection of which window/instance of Inventor to open it with, instead of having to navigate our complex folder structure in "Open from Vault", or right-click and "Go to Working Folder", then locate the file among several within the folder and drag-and-drop it to the Inventor instance desired.
In some cases we need two different projects open to compare, and it is useful to have multiple Inventor sessions working in parallel.
Thank you.
