I could not share files in Pro DC and also can't convert my files using the panels. Tried many of the solutions here but to no avail.
Then decided to uninstall it and was prompted with the message:
"This patch package could not be opened.Verify that the patch package exists and that you can access it or contact the application vendor to verify that this is a valid Windows Installer patch package"
Additionally, I also got another error - 1635 before deciding to install.
