Installation error

My installs over past few updates throw up this error (attached) when install is almost complete. By clicking OK on the error message install completes and all is good from there. Any idea what may cause this?
Cheers Bryan.

Magnified…

Does that still happen if you right click the Weather Watcher installer and choose “Run as administrator” to run it?

I have solved the problem have allowed WWL access via controlled folder access, it was restricting the program from installing, even though it was installed! Windos 10. Thanks Mike.
