The X1 Professional Client version 6.7.4 relies on the Microsoft .Net Framework 4 Extended version. Most systems have the Microsoft .NET Framework 4 Client Profile version installed but please note, systems may not have .NET framework 4 Extended version installed.
Prior to installing the X1 Professional Client version 6.7.4, please confirm whether you have Microsoft .Net 4.0 Extended installed. To confirm, navigate to Control Panel > Add/Remove (or Programs and Features). If you have .NET Framework Extended version installed, you will see “.NET 4.0 Framework Extended” listed amongst the programs.
