2. Click Next.

3. Once you have read the terms of the EULA, check the box to accept the terms and click Next to advance.

4. Select the roles you want to install on this machine Functions Management Role and/or Functions Worker Role and click Next.

5. Click Next to have the Azure Functions Runtime Setup Wizard begin the installation process on your machine.

6. Once complete, the setup wizard launches the Azure Functions Runtime configuration tool.
