Hi All

I upgraded from Windows 10 to Windows 11 recently. After the upgrade, I got 3 updates to .NET Framework. Below are installation dates and update information.

Oct 28, 2021: 2021-10 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5005537)
Nov 07, 2021: 2021-10 Cumulative Update Preview for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5006363)
Nov 13, 2021: 2021-11 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5006363)

Prior to this, my last update to .NET framework in Windows 10 was the below.

Oct 22, 2021: 2021-10 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 21H1 for x64 (KB5005539)

I started facing issues with applications that use the .NET Framework from the Nov07, 2021 update onwards (2021-10 Cumulative Update Preview for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5006363)).

2 applications in particular are throwing the errors.

  1. Citrix Receiver:

This application requires one of the following versions of the .NET Framework:
.NetFramework,Version=4.6.2

  1. Lenovo Vantage

This application requires one of the following versions of the .NET Framework:
.NetFramework,Version=4.6.1

There is a question in that error that says "Do you want to install this .NET Framework version now?". When I say to that question, it takes me to the latest .NET Framework (4.8) page.
When I try to download and install it, I get another message that says ".NET Framework 4.8 or a later update is already installed on this computer."

Now I am unable to use Citrix (vital for connecting to work).

I have tried rolling back the Nov 07, Nov 13 updates (KB5006363). That didn't help.
I reinstalled them back again using Windows Updates. That didn't help.

I am stuck.

Can someone please suggest a solution or remedy that I could try for this?

    Applications that are developed for .NET Framework typically require that a specific version of .NET Framework be installed on your system. In some cases, you may attempt to run an application without either an installed version or the expected version of .NET Framework present

    I would suggest you to follow below Microsoft guide to remediate.
