I have an entire project of Inventor files that a customer sent me. Solidworks won't open them. I downloaded Adesks, Inventor Viewer and that gives an error as well. When I look under the iproperties of the file it does not give a version that they were created with. Supposedly this means they were created with a version newer than the version on your system. The Inventor Viewer is 2019 version.
Anyone have any tricks that I can try to either find out what version these were created in or find a viewer/importer or something that I can see them or import them into SW? It would be nice to be able to get them open as models but not entirely necessarily. If I can view them I can work around it.
