Update to Dorico 5.1.40

When I’m installing the update to the latest version in Windows 11, tells me can’t continue because I don’t have direct access to the WEB HELP directory.
What I should do to correct this?

Can you attach a screenshot of the specific error message you’re seeing? There’s no folder called “web help”, though there is a small executable called “Dorico Web Helper”, which is used to provide the local web server that spins up when you choose Help > Keyboard Shortcuts in Dorico.

Try restarting your computer, and then running the Dorico 5.1.40 installer before you run any other applications. That should ensure that anything that was in use when Dorico was last running is now free.
