Hello RodWa and welcome to the Autodesk community!
It looks like you are stuck at the activation/installation step while attempting to download software, or are having problems with starting your software immediately after installing.
The following article(s) should help you resolve the problem:
Communication Failure message during download and installation - Note that this article also provides
alternate downloading and installation methods.
Application Manager Update stuck at installing
In order to manually activate your software (in cases where the activation appears stuck), please refer to
Manually Activating Your Autodesk Software.
If the activation window is not displayed, others have resolved this by completely uninstalling and reinstalling their software. Please refer to
How to Remove all Software from a Windows System for assistance.
