Desktop beta app will not uninstall

I just did this and it's not working at all. Every time I try to install it again, it says it's already installed. I dumped temp files, looked for anything associated to EA on my pc, and from what I found it didn't work.
Used control panel, and Revo, used CCleaner, nothing. It still says it's installed. This is aggravating, and EA support has been completely unhelpful.
