I'm getting an error saying the .NET Framework is missing. | SketchUp Knowledge Base

The PC version of SketchUp Pro requires the Microsoft .NET Framework 4.0 (2.0 for SketchUp 8, or 1.1 for SketchUp 6). During install, SketchUp will detect if the correct version of the .NET Framework is missing and will prompt you to download and install
