We understand that some of our clients' customers are often running older versions of Microsoft .NET frameworks, so here is a little rule of thumb for what version(s) are required to run the latest version of Ground2Cloud for Quickbooks.
Our latest version of G2C (Ground2Cloud) requires that you run at least a Microsoft .NET framework 4.7 to support all the latest features released by QBD SDK. This requirement is not Ground2Cloud specific, but rather a QBD SDK requirement.
You would be able to use an older version(s) of Microsoft .NET Framework, however, it will require that you also use an older version of our Ground2Cloud connector (SDK) which may or not raise some limitations in features supported. It is also important to highlight here that Microsoft allows multiple versions of .NET framework to be running on the same machine, and it would allow you to run different versions for different applications/software, therefore allowing you make use of our latest version of Ground2Cloud.
