We now see an error message that eDrawings Viewer "can not open files created before Solidworks '97 Plus". The files we're trying to view are all from 2015 and opened just fine before our upgrade to Sierra. Hoping to confirm that this is a known issue and not something simple that we might be overlooking? Any help appreciated.
ADDENDUM: I should add that we used the viewer successfully in September of this year (2016) to view these same files but were running an earlier OS.
