Download
Get the official installer for 64-bit Windows 10/11. Its filename is nogada-app-setup.exe.
For a new installation, follow Installation and License activation. If you only want Telegram, start with the bot; no app installation is required.
If the app is already installed, use the update notice or Settings → General to check for updates. Finding an update is not the same as completing installation. Check any running tasks before applying it and follow the on-screen instructions.
If security software blocks the file, check the warning and download source, then contact the operator. Do not assume the warning is harmless or disable antivirus protection.
