what does this mean? I tried manual patch,

Well game can't be patched if you have client running... Just close it and try again x.x 
If game is closed and the message still shows up, kill elementclient.exe in the task manager or restart your PC

Linux/Mac can't execute .cup files. That's why people use PlayOnLinux/Mac and have to re-install their game instead of patching (Regarding second screenshot). If killing the process doesn't work, re-boot your PC and try again; that should work.
