I have look at tons of comments and suggestions about solving this ClickOnce Setup problem but have NOT found a solution.
Advanced Security check did not work because the item "warn if changing between secure and non-secure mode" is not checked!
The URL for the .application file is correct.
I have deleted the ClickOnce files and folders several times and republished the application in Visual Studio but that didn't solve the problem.
Can someone suggest a solution that is tried and true?
Thanks.
