NSudo is a pure native Windows desktop application, so you don't need to install .NET Framework. But NSudo has provided the .NET SDK to the developer. I will test with the MSMG Toolkit.
I have tested it and it's OK. And the "start.cmd" in MSMG Toolkit is execute "toolkit.cmd" with NSudo.
I am using Windows 10 Pro for Workstation (19042.985), Windows Feature Experience Pack 120.2212.2020.0 and .NET Framework 4.8. Download the latest stable version of NSudo from the official website and tested it. Which version of NSudoLG you are using? x64, x86 or arm64? Which command line you used in NSudo or input in the NSudo GUI? Also please don't disable the Windows Modules Installer (TrustedInstaller) service.
NSudo 8.1 Preview It's not the final version. It's only for testing. Starting from NSudo 8.1, The logging support has been introduced. You will see the detail log when you met the error like "Create process failed." in NSudo. Here is the changelog. Kenji Mouri
@DennyAmaro @_kod0k I am trying my best to reproduce the issue on my machine. I also wonder to know the Windows version and SKU installed in the device belongs to @DennyAmaro .
I have mentioned "For helping the users to create the NSudo context plugin, NSudo 9.0 will introduce a useful plugin as example. (It's a plugin for system optimization.)" in https://forums.mydigitallife.net/threads/59268/page-28#post-1666941. Here is the screenshot for one of the features called "Update AppX packages", and implemented features of current development stage and x64 binary size of that plugin. Kenji Mouri
