Dear Jan,
Thank you for your query.
Is this a Revit API issue, or an end user question?
Are you doing anything programmatically, or just using the standard Revit user interface?
I guess the latter, since I have no idea what what you are talking about.
If you are not doing anything programmatically, this is not the best place to ask such a question.
Please note that this discussion forum is dedicated to programming Revit using the Revit API.
Therefore, you cannot expect an answer to a question such as yours relating to installation, product usage or end user support issues here.
You should try one of the non-API Revit product support discussion forums instead for that:

The people there are much better equipped to answer your question than us programming nerds.
I hope this clarifies.
Thank you for your cooperation and understanding.
Best regards,
Jeremy
