How to ensure that your .NET Framework is up-to-date
Method 1
Re-install NDU via the latest program installer available for download from our site
(this will also install the latest version of the framework):
https://norgatedata.com/downloads.php
There is no need to uninstall NDU first. Before running the installer, just make sure that NDU is closed and any integrated 3rd-party application (like AmiBroker) is closed. Also, make sure that you are running the latest installer and not an old one that you downloaded previously.
Method 2
Install .NET Framework v.4.8 by getting it directly from Microsoft:
https://dotnet.microsoft.com/download/dotnet-framework/net48
On the Microsoft download page, click the link to "Download .NET Framework 4.8 Runtime". Then locate the downloaded set-up file and run it.
