Hi @yaser.alipoor ,
Is this a Revit API question or a Revit product question?
Please take a look at this below link
If your question is related to the Revit product UI, 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
The people there are much better equipped to answer your question than us.
I hope this clarifies.
