Good Afternoon,
You may encounter issues moving to Windows 7 as the Pervasive Database Engine will probably not work under the new Operating System.
The only version of Maximizer that fully supports Windows 7 is Maximizer CRM 10/10.5. If you are using the Maximizer 9 Pro edition you can upgrade it to the Maximizer CRM 10 Entrepreneur Edition on our webstore:
