Hi Fred,
same problem than 1.96, the installation is fine, all files updates, but the main .exe file is no copied to the installation folder.
I had to install in another machine win11 x64 and compare the content in the folder for arm64, and seen than all files has been updated, except the bointask64.exe.
for the time being I had copied the new exe to the installation folder and now running 2.0 in windows 11 arm64.
already told, bear in mind, that x64 programs are emulated and running in windows arm64.
