When you open the installer on Windows, you might get this warning message. You will be presented with a "Run" and a "Cancel" button, but the "Run" button may not actually work. If this happens to you, please click the "Cancel" button and then right-click the RuneMate installer, and run it is Administrator. This will give you sufficient rights to install RuneMate without any issues. @Arbiter would it be possible to allow image uploading on the RuneMate servers? If you don't want that, you could perhaps look into the Imgur API which would allow users of this Forum to upload images which are stored on Imgur's servers, instead of RuneMate servers.
