After the program is installed, please do a windows update.
Also make sure you do the update version in the picture. Picture to click.
Note: Definitely do not have or open debugger(httpdebugger,x64,dnspy,etc...) programs. If Checker catches these programs, it will take a screenshot and ban you from that device. If you get banned checker will be closed permanently in which case you need to reinstall your rdp so be careful.
