I've just installed an ePO 4.5 PAtch3 onto a Russian Windows 2003 Server SP2 successfully. I get over the login screen where everything is in Russian and even the Language is set to "Anglitsky" (pronounced).
From then on the default dashboard has mixed language elements: all the queries are in Russian and all the non-query elements are in English. The name of the dashboard is also in Russian.
I can live with it, but would like to know if this should be this way or not? I would guess when a language is chosen it should apply to everything...
Any ideas or similar experiences (with other languages vs English, too) ?
Unfortunately not - the language of some elements, like query names and so on, is effectively hard-coded to the regional settings used at install time
I believe this is going to be addressed in a future version, but I don't have any details.
