"ClickOnce does not support the request execution level 'requireAdministrator.'"
So I was writing an application that requires access to the registry.
I had not touched any build settings, wanting to get the thing working before I added the other touches, such as a description or name.
Out of the blue, I get an error that will not go away. ClickOnce does not support the request execution level 'requireAdministrator'. Now, I hadn't touched ClickOnce in this application. All I had done was include a manifest file requesting these permissions.
My problem now is that this error will not go away, and I cannot compile my program. Any advice on what to do? (Side note: I am about to go to bed, so I will check this tomorrow afternoon).

Edit: This comment gives a good answer, too.
Click once appears to get enabled whenever you click "Publish", whether you want it to or not! If you are using "requireAdministrator" then it appears that you cannot use ClickOnce, and therefore cannot "Publish" your project.

Turns out that under the Security tab, "Enable ClickOnce security settings" was checked. Even though I didn't check it. Anyway, unchecking that stopped ClickOnce giving me errors. That took a while to find...
