Hello list,

thank you all for your advices.

Aditya was right. There was some mess in PATH variable.

Lesson learned: start with explicit paths to executables.

Still where mtxrun (Windows) was pointing to the right one, which was fooling me.

I've noticed the problem with antivirus SW during the first installation of lmtx.

It wasn't the case this time, but one should be aware antivirus programs don't trust mtxrun.exe.

Thank you once again,

Jano

Do you have an anti-virus product installed?

In the past I've noticed that Symantec sometimes gives a false positive on some of the ConTeXt files as they are installed and silently deletes them thinking they contain malware.

The result is a broken ConTeXt because files are missing but you have no idea which files are missing. :-(

Try temporarily disabling AV and then do a complete re-install into an empty C:/data/context directory.
