Products

• IT Management Suite

Issue/Introduction

You have a Windows Server 2019 that needs to be upgraded to a newer version of the Symantec Management Agent and its plug-ins. While trying to upgrade the Task Server Client, the following error window popped-up:

InstallUtil.exe - This application could not be started.

This application requires one of the following versions of the .NET Framework: v4.0.30319

Do you want to install this .NET Framework version now?

Environment

ITMS 8.7.x

Cause

This is actually a message returned by Windows when our Agent installation process is calling some Windows APIs.

It is a known issue seen by other people in different scenarios. The problem is caused by not having all the proper .NET references in the registry.

See:

https://techcommunity.microsoft.com/t5/windows-server-for-it-pro/windows-server-2019-and-net-4-8/m-p/3840420/highlight/true#M9922

https://www.bleepingcomputer.com/forums/t/758800/net-48-kills-server-2019/

Resolution

Per the previously mentioned online references, the solution is to take/import the .NET Framework Reg Keys from a similar Package Server / Task Server that is running Windows Server 2019 and has .NET Framework 4.8.0
