The real fix is reducing the textures or whatever it is that fills your 500 MB. Or else, distribute a RAM expansion together with your game.


You missunderstood me. The problem is not, that the game does not run on PCs that do not have enough RAM or that the requirements are to high. No, that works fine so far. Our Problem is, that even though a PC has 1024 MB or 2048 MB or even more RAM and a sufficient enough swap file, the game does not start but instead throws the Not Enough Memory Error.

Anyway, we managed to reduce Nexus size to 200MB. Will this solve the problem?

Again, please understand: machines on which this error occurs have sufficient RAM, but the error appears despite of that.
