GLOBODOX requires Microsoft .NET Framework 3.5 (which includes .NET 2.0 and 3.0). On Windows Server 2019, .NET 3.5 is an optional feature that is disabled by default. This guide walks you through enabling it on Windows Server 2019.
Make sure you’re signed in as an Administrator. These steps are for Windows Server 2019 Desktop Experience. If your server can reach Windows Update, you don’t need the ISO. If you use WSUS or have no internet, you’ll point to the installation media instead.
Open Server Manager (flag icon on the taskbar or Start menu).
Click Manage → Add Roles and Features.
Installation Type: select Role-based or feature-based installation, then Next.
Server Selection: pick your server, then Next.
Server Roles: don’t change anything → Next.
Features: tick .NET Framework 3.5 (includes .NET 2.0 and 3.0) → Next.
If you’re asked for a source (or you know you’re behind WSUS):
Click Specify an alternate source path (bottom-left).
In Path, enter: D:\sources\sxs
(Replace D: with your mounted ISO, or use a network share like \\fileserver\win2019\sources\sxs.)
Click OK to return to the Confirm page.
Tip: If your server can reach Windows Update, you can skip the source path and just install.
Click Install and wait for Installation succeeded.
(Optional) Verify: Open PowerShell (Admin) and run:
Get-WindowsFeature Net-Framework-CoreIt should show Installed: True.
