Revit 2017 project upgrade issues

[Anonymous]

Cannot open a central Revit file once updated to 2017 from 2015.

Any Ideas?

Hi, I am sorry for the inconvenience! Can you please share the Revit model with us, so that we can take a look at it? If yes, please send me a message (click on my name on the left side and click "Send a message"), and I will give you directions how to upload and share the model.
