if you have
that version of winex that its command is "wine" then you will not be able to get regular wine to coexist with it...
so either
a) get a different copy of winex, or
b) just forget about it, cause there is next to no point in doing this...
i can't see it working if you renamed the execuatble wine to be winex, cause i would think you would have to also modify code that it links to...
the only thing you could pull off would be to make an alias so when you type winex it will run wine, but then it would still conflict with the regular wine when you try to install it, so personally i think you shouldn't even bother, cause i know myself that anything that i could run in wine ran in winex, but that could be just me
