I already tried admin and I always install to a non-default place.

btw, I usually get a new laptop each year and have had this issue with almost all Matrix games at some point since 2013. I have just worked around it.

Yeah, I got it. But that updater has continuously had issues in all of my Matrix games.

I get an error that the game can't download the patch. I have these issues with the Slitherine/Matrix updater all the time. It say something about "can't execute line 44" as an error message.
