Download and use
Download the zip from Releases, unzip it anywhere and run miniVNA Tiny.exe. Nothing is installed and the program only looks on GitHub for a newer release (one small request, switch off with the tick box in the top bar). The User Guide PDF is in the zip. The exe is unsigned, so Windows SmartScreen may ask you to confirm.
