The error message might be related to registry access issues or corruption of the ClickOnce
setup store. The ClickOnce
setup is used by AppBuilder Windows client
for installation and updates.
The above said, I believe that deleting the ClickOnce
cache should resolve the issue. You can do that by deleting the content of the %localAppData%\Apps\2.0\
folder. Additionally, I'd suggest following the whole procedure for the Completely Uninstall the Classic Windows Client
article before reinstalling the client.
