When opening a project in Workstation for Projects, Unkown Exception error will pop up
Workstation for Project
This is a defect for SmartStruxure 1.5. When there is no Internet connection on this computer, this error will happen.
This issue will be fixed in SmartStruxure 1.6. Currently the workaround is to obtain the Internet connection for this computer, at least when opening the project. It should be OK to remove the Internet connection after the project is opened.
