Dear Dale,
Is this a Revit API issue, or an end user question?
Are you doing anything programmatically, or just using the standard Revit user interface?
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 understanding.
Best regards,
Jeremy
