So we currently have an issue with the plugin where in some cases the wizard will not find 2023 installs of Revit without another old Revit install on the machine.
The fix did not make it to 5.0.2, but will be in 5.0.3.
A couple things you could try :
- Update your .NET Framework to at least 4.5.2 (see Download .NET Framework | Free official downloads)
- If you have a way to install Revit 2018.3 to 2022, and report back if you were able to install.
One last question : did you have an older version of Revit installed before, with the 5.0 or 5.0.1 Datasmith plugin ?
Cheers,
Antoine
