Sorry to hear about your struggles.
Unfortunately, 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
