Uhm… and I confirm che the new binary contained in the zip DOESN’T start on winxp (I have winxp SP2), while the old one (with the installer) yes.
The old one, during execution, often reports the error “This application has requested the Runtime to terminate it in an unusual way”. (But in this second case there is a trick to avoid the problem: simply you need to don’t touch that window and focus again the game. You will continue to play without problems).
So I start to think that probably win7 and winxp builded executables could be somehow incompatible. A solution could be (I think) the one I will now explain.
Create two zips for windows: One for winxp and one for win7. I will try to make a build for winxp SP2. If it will work I will give it to you. If someone that have just builded the xp version, perhaps could be a nice idea to share it.
As I said. It is not a such problem for me (I have the old binary that somehow works… now I know what to do to play and to use editor) but however can be for all xp users
