We have not extensively tested Jolicloud, but on cursory installation tests Crossover seems to work as expected.
Jolicloud 1.0 is an Ubuntu-based distribution, and so we recommend that you use the .deb (Debian) installer package. When you double-click on the .deb installer (or right-click and look for "open with"), Gdebi should open up the package and offer to install it.
After the installation, you'll find that Crossover doesn't readily appear in Jolicloud's menus. To see Crossover's menus, and the launchers for Applications installed in Crossover, push the "menu" key on your PC's keyboard. This is the hotkey in Jolicloud for bringing up the Ubuntu GNOME menu, which will contain Crossover.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
