Once the download completes, locate your downloads folder and double-click the RestSetup.exe file.
Windows might warn that the application is downloaded from the internet. Hit "Run".
Follow the steps of the installation and wait for it to complete. The high quality graphics included with Rest may take a while to download.
Rest should run automatically after the install has finished. If it doesn`t, look for it via your Start Menu`s search.
You will now be prompted for your license key. If you don`t have one, just hit "Continue trial" and you can evaluate Rest for up to 7 days, for free.
That`s it :)
