[NTG-context] module installer: unknown script 'install-modules.lua' or 'mtx-install-modules.lua'

Hi, I'm setting up a new computer, and I've wanted to benefit from the new module installer. However, the commands I should use gives me the following error message : mtxrun --script install-modules --list mtxrun | unknown script 'install-modules.lua' or 'mtx-install-modules.lua' I'm using a fresh context installation (2023.05.08 17:39) on Windows. I've see a couple of others had/have( ?) the same issue. It does not matter from where I run the command (i.e., I'm getting the same error message also from inside context\tex) Is there anything I should do to make this work? Best, Denis
