Describe the bug
I wanted to try the new print tool.
I have used Revit 2020.1 opened as english version, using the rac_basic_sample_project.rvt
Created a plan schedule (I couldn't find an example for the "Sheet Index Schedule")
As soon as I click on "Set Print Settings" I got an error.

Would you mind sending me a snapshot of the Revit about window that has the version and build number? For Revit 20.1.1.1
Thanks for the error. I can replicate this and am looking into it.

Resolved.
@Thomas84 Seems like this is a language-specific Revit release. I don't see it here in my north-america autodesk account. Do you have a link to the release notes? similar to this

Nope. I have that installed but it didn't increase my version number
