Revit Can't open a C4R project if another version of Revit is open

[steveperkio]

I'm unable to open a C4R model in one version and then open another C4R or local file in a different version. It seems that having two different versions of Revit open at the same time interrupts the connection to BIM 360 which then doesn’t allow syncing of work.

I have had ongoing problems with this since 4-7-2017 with Autodesk involved to some extent and resellers involved the rest of the time with no results..

Reading some forums it looks like we are just out of luck and must work with one hand tied behind ones back.

I don't have the luxury of working on one model during a day and often need 2 or 3 models open for meetings and modeling during a meeting (with other meetings stacked up at the same time or one right after another).

This needs to be fixed someway if possible as it's holding me back from being productive.

Unless I am wrong, I believe you can only assign one license of c4R per account.  So it is working as it should, as opening multiple versions of Revit utilizes multiple licenses.  At least that is the case if you are on a network license.
