How to change Access language

If you have say Russian version of Access installed, and for some development you need an English version - there is a easy way to change language version - you need to find a MSAIN.DLL file in OFFICE11\1033 folder on a PC where English Access installed, and copy it over same file in OFFICE11\1049 folder of Russian Access. Don't know if this is a supported way of doing this, perhaps there are a better way, but at me this works fine since Access 2.0
