Hello, Hurray!!! The recent Windows minimals work fine for me! Thank you, Mojca, for showing a hidden place in the garden! :) And my a kind of installer works too, how nice! :))) A few words about my 'installer' (maybe someone is interested). It does the same job as setuptex.bat, but sets variables globally by writing into registry instead of dos box. So I can call binaries from any application and it all works!. (Remark: merely setting the PATH variable is not enough, dozen other are needed. Vars were typically defined in texmf.cnf files, but I was surprised to find that those files are explicitly ignored by luatex. ) My next step is to create 'real' installer for Windows. I've discussed this idea several times here and feel that people need it (I do :) My vision of the installer is: install-and-forget on any Windows machine. Target audience: novices. It will include mimimal distribution (56Mb), install or require Ruby too (not included in minimals?). This installation will NOT be able to coexist with MikTeX or TeXLive, because settings will clash. That's all news and thank you all!! Best, Vyatcheslav Yatskovsky
