Revert ClickOnce applications.

Sometimes things don't goes as planned doing a new ClickOnce Release.

To revert back to the next newest on the web server do as follow:

There will be a 'Application Files' folder at the root, open the next newest and copy 

<YourApp>.application file THEN go back to root folder and overwrite the <YourApp>.application located there.

Now you can remove the version folder under 'Application Files' for the bad version.

Next

Open the index.html (could be namned something else) file in the root folder, look for version and correct it to what you selected from 'application files'.

Done, next fix your broken application :)
