If you Install and run Insightful on Windows 7 and the software does not start, please try the following::
Download .Net Framework 4.0 Runtime https://dotnet.microsoft.com/download/dotnet-framework/net40
Install .Net Framework 4.0 Runtime on your device
Reboot the computer
Note: As dotnet 4.0 reached end of life and is no longer supported, similarly to how Windows 7 is no longer supported by Microsoft, some users might be experiencing difficulties with installing / updating to version 4.0. If you are among them please find links to other versions on the bottom of the web page linked above and try with dotnet version 4.5 instead.
