This has nothing to do with any of that. If it merely extends to the help menu, it usually means one of the following:
- the community help client was never properly installed and thus DW can't display any help topics
- the update manager was not installed properly or is doing something weird liek updating anotehr Adobe app and never finishing
- there is something wrong with your licensing system and it cannot display tha Activate/Deactivate/Subscription and whatever options
All of this pretty much boils down to mundane permission issues, but since you didn't mention your operating system and system specs, nobody can advise more specifically. inm any case, uninstall, run the Creative Suite Cleaner Tool, restart the system, reinstall again, restart once more and see if it works then. also make sure to configure the community help client accordingly after the install...
