Is this .exe file compatible with 4.10?

Yes, apparently it is. I've applied to my copies of 4.10 and everything works fine.

Actually, this 4gig mem mod works with other Windows programs as well, not only with Il-2. I've applied it to my graphics editor which sometimes suffered issues when working on large sized files for maps ...

Just make sure that before applying the mod, you make a backup of the .exe you wish to mod. The mod automatically makes a backup when it runs the mem mod, but you can never be too sure about such things.
