Set Windows application to use a different language than the OS default
By default Crossover will get your language and format style from the host operating system. You can manually specify a locale by editing the cxbottle.conf file located in each bottle Crossover creates.
To locate the cxbottle.conf file click the Bottles button in the top-left of the Crossover window, select the appropriate bottle, click the gear menu in the bottom-left and pick Open C: Drive. Go up one level to find the cxbottle.conf file on same directory level as the drive_c folder.
In cxbottle.conf under the EnvironmentVariables section add a new entry for the locale you want to use. For example to set the bottle to Russian you'd enter:
"LC_ALL" = "ru_RU.UTF-8"
Locales that should work are:
These are the UTF-8 locales that are present in OS X's /usr/share/locale/ directory, which the "legacy" directory that wine uses for locale information. Other locales not listed above (for instance, es_MX for Mexico or es_GT for Guatemala) will not work at present.
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.
