If you are trying to install Graphical Analysis to a single computer, we recommend the regular installer, which is free at
https://www.vernier.com/products/software/graphical-analysis/

If you are an IT professional at a school and want to install Graphical Analysis to a large number of computers managed using tools like Group Policy or SCCM, read below:

Download the silent installer (MSI) for Graphical Analysis.

Notes:

You also need to install the 2017 Microsoft Visual C x86 redistributable in order to run the application. That installer is included in the zip file and can be installed silently with “vc_redist.x86.exe /q”.

On Windows 7 you must install KB2921916. See
