Unfortunately there was a bug in Revit Importer 1.2026.1.0 on non-English Windows with non-English SketchUp where the import failed.
We have therefore had to roll back the version on Extension Warehouse to the previous release (1.2026.0.0).
We are currently working on a fix, but in the meantime, English users can get 1.2026.1.0 from Trimble labs
EDIT: Futher updates on this will be posted in Revit Importer 1.2026.1.0 failing for non-English usage - #6 by daniel_pidcock
