The Demo version is free, but has a limited duration license. You will need to come back here every couple of months to download a new installer if you want to keep on using UVLayout.
Download and run the EXE file below to install the Demo version of UVLayout for Windows platforms. See Installation_Guide:_Windows for full installation instructions.
After installation, you can run UVLayout by drag’n’dropping OBJ files onto the “UVLayout Demo” icon.
