Problem with language, missmatch German and English

Hello

We've the following situation

Solidworks EPD Installation with Archive Server in Switzerland, Version 12.04.0813, the Installation of Solidworks and Server OS is in German.

Solidworks EPD Installation with Archive Server in Manila (Philippines), Version 12.04.0813, the Installation of Solidworks and Server OS is in English.

Between the sites we don't have a domain trust but we've a vpn tunnel for data replication, file check in and check out.

Following Problem:

When I connect on the Server in Manila and I'm starting PDM Administration on the Server in Manila the menu sometimes is opened in German and sometimes it opens in English.

I don't know why and when this issue will occur, it's only sometimes and this ist not a big problem. The big problem we've is that the tresor configuration on a workstation in Manila only opens in German, also the menu in tresor on local disk is in german but we've installed the program under windows 7 in English.

We don't understand why we've this problem in Manila, the Server, Workstation and the PDM installation was done in english. Only in Switzerland the installation is in german, but can this realy be a problem with the vpn tunnel? is it possible that the system in manila takes the settings from switzerland without to take care about the local installation in english?

We set the language in pdm administration to english, but the user in manila still has it in german.

May be someone had this problem an can help.

Thanks in advance

Thomas
