When installing GeoStudio 2007, you receive an error message that the .NET framework must be later than version 2.0. You are running the latest operating system (i.e. Windows 10) and your .NET version is 4.0 or higher.
The error message is confusing because your .NET version is higher than the recommended version needed for the software.
The version of .NET that comes with your operating system does not include the necessary files for the older versions of .NET. This means you will need to enable the older versions of .NET manually for the software to install.
Please refer to the following Microsoft .NET framework installation guide for instructions on how to proceed. Then continue with installing GeoStudio 2007.
