Original site androidremotepc.com is down so people cant use bluetooth remote pc by Rozky, either free or paid version, because thay cant download the pc side app. Luckly I still have the file here remotepcserver-2.0-win32.zip
Just click view raw, or download raw file
Update: Looks like they are completely out of business. Now I can't even find the app in playstore. So sad 😥
