I just upgraded my "portable" installation of Beta 14 from 13. I am running Windows 10 Business 21H2 19044.1586 64bit.

During installation it asks for .NET update, but then when I download and install .NET and even reboot after installation, the installer asks again for .NET. My installed .NETs are:
2.0.50727.4927 Service Pack 2
3.0.30729.4926 Service Pack 2
3.5.30729.4926 Service Pack 1
4.0.0.0
4.8.04084

I don't want to install using MSI, as I use this laptop both docked (using a Lenovo Thinkpad USB-C Gen 2 40AS0090US) with two 1080p monitors attached, and undocked where I don't want DisplayFusion running at all.

Also, what are your thoughts about using the Klite Mega Codec Pack which updates FFMPEG and other codecs DisplayFusion uses?

Thanks

Those are versions of the .NET Framework.

You need .NET(Core) 6.0.
