Grapher 12 requires the Microsoft Visual C++ Redistributables for Visual Studio 2015 to be installed prior to Grapher installation. If your machine does not include these runtimes, the Grapher 12 installer will install them on your machine prior to installing Grapher.
If you receive an error that Grapher is unable to install the redistributables, you should:
- Cancel the Grapher installation.
- Manually download both the x64 and x86 files from Microsoft and install them.
- Run the Grapher installer again. Grapher 12 will then install.
