Beginning with Tax Year 2020, both Lacerte and ProSeries will require Microsoft .NET Framework 4.8. Microsoft .NET Framework 4.8 is only supported on Windows 10 (Version 1607 or higher), and Windows 8.1. Since .NET directly interfaces with the Windows operating system, it is recommended that these steps be performed by an IT professional.
Please note that due to the integration with the operating system, our support teams cannot assist with Windows Update, or .NET 4.8 installation issues. If an issue arises, please contact a local IT professional, or Microsoft support.
