The Prerequisites for Jet Express are low. If your Microsoft Dynamics GP, office and Operating system are on a supported version then you will be able to run Jet Express. The only item that may need to be completed is verifying .NET Framework 4.5 is installed. Here are the following requirements from Jet Report’s website.

Database: Microsoft Dynamics GP (Version 9.0 and Newer)
Microsoft Office: Microsoft Office 2007, 2010, 2013, 2016, Microsoft Office 365 Desktop Edition
Operating System: Microsoft Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Vista, Windows Server 2008 through 2012R2
Prerequisites: Microsoft .NET Framework 4.5**
**Microsoft .NET Framework will be installed with Jet Express.
