You will need to install the .net version it is asking you for.
In Windows 10, go to:
Control Panel --> Programs and features --> Turn Windows features on or off (in the upper left corner)
once that window populates, click in the box that says ".NET Framework 3.5 (Includes .NET 2.0 and 3.0) you don't need to select the 2 sub-headings under that main one.
Click OK, and it will be installed.
