[Wine] Installing a program from an iso img

[Darknight]

Hi guys, well new to wine so forgive me :)
Ok made some blank wrapper easily and ran some windows demos, well chuffed there also re configured some settings to make them run full screen, so i thought ok, doing well here.....
Soo long story short, i downloaded a windows iso of sins of a solar empire trinity, as the demo work flawlessly.
Thats where my problems started, i mount the image easy enough just by clicking on it but the exe file is not recognised,  is it possible to find allready made wrappers that you can download for this game? Or i would like to learn to do it myself.
Thanks for any help....and patience.
