Russian Language Module Problem

I have a problem with the Russian language module.

It shows not installed, yet it is because you can select it via the footer.

When looking into the modules and trying to install I get this error.

Installation of: Russian Language Failed

I need to remove the language from the site because of 3rd party missing languages and this is how I found this error.

What do I need to do?

WOW, ghost town or what?

Go to sys_localization_languages and delete the row with the Russian language,  using phpmyadmin or run this query

DELETE FROM `sys_localization_languages` WHERE `Name` = 'ru';

warning : before deleting from sys_localization_languages table grab the language ID to delete any language keys from:

sys_localization_strings table  and run this query:

DELETE FROM `sys_localization_strings` WHERE `IDLanguage` = 'your_IDlanguage'; remember to change the your_IDlanguage by the correspondent number.

the last but not the least delete from sys_localization_categories table the row corresponding to russian language, your done.

THANKS!
