Unable to Install ARticulate 360

HI,

I am trying to install a new version of Articulate 360 (Windows 11) and apparently there is a conflict with the previous version that I was trying to uninstall. Here is my sequence:

• Unistalled 360 it through the Unistall app, then rebooted and the app did not appear in the list of programs.
• Downloaded the package with the software
• opened Articulate. Near Storyline the option was available: install updates. Clicked. then the dialogue started and the message was saying that the path wasn't found.
• When I click on Open Storyline, I get a message there was an error opening and new storyline I have now Unistall failed. 

Any advice would be  much appreciated
