If "Windows protected your PC" appears
Click "More info" and then "Run anyway". The program is the official RustDesk - you will see its publisher signature.
Allow changes to your computer
Answer "Yes" to "Do you want to allow this app to make changes?" - the technician can then also control windows that need administrator rights.
Read the ID to the technician
The program window shows your ID (9 digits). Tell it to the technician over the phone, no password is needed.
Click “Accept”
When the technician connects, click Accept in the RustDesk window. No need to read out the password.
Done - the technician connects
You see the connection in the program window. Close the program when finished - the connection ends and the password stops working.
Run the downloaded installer
Open the Downloads folder and double-click GRIS-vzdialena-podpora-instalacia.cmd. If the browser holds the file back, choose "Keep"; if Windows shows "Windows protected your PC", click "More info" › "Run anyway".
Confirm administrator rights
The installer runs as administrator - answer "Yes" to "Do you want to allow this app to make changes?".
Wait until it finishes
The window "GRIS - vzdialená podpora - inštalácia" goes through steps 1/4 to 4/4: downloading the program, installing the service and configuring it (usually under a minute). At "4/4 Hotovo" (done) close the window; if a red error appears, please call us.
Done - the technician will call you
The program runs as a service, even after a restart, and only our technician knows the password. The technician assigns the device to your company and calls you; nothing else needs to be set up.
