could you provide me your NppShell_06.dll so I can make sure it's arm64 architecture ?
Also, which ARM package do you download? The URL please ?

Of course.
NppShell_06.zip

I've downloaded the installer from here: https://github.com/notepad-plus-plus/notepad-plus-plus/releases/download/v8.1.5/npp.8.1.5.Installer.arm64.exe

I installed v8.4.4 and the installer attempts to call multiple instances of Microsoft Register Server (regsvr32) eventually locking up the machine (exhausting available RAM). I tested this with Windows 11 Pro (22000.832) on a Lenovo X13s (Snapdragon 8cx Gen 3, 16 GB RAM).
Seems this issue is worse than the originally depicted behavior as it now has the potential to make the current session unusable.
