I'm already working some time with MOSS 2007 (Microsoft Office SharePoint Server) and have installed the beta 1 and beta 2 versions of the product. Last week i had to reinstall MOSS for some reason and got into problems.

Every time when you try to run the configuration wizard i got the following error:

Failed to create the configuration database. Reason: The language is not supported on the server.

After googling and thanks to a few guys there i found the solution. You have to make some registry changes before running the configuration wizard again. If you have choosen the "advanced" installation containing farms you have to remove two databases from SQL Server 2005.

The fix is:

• Start regedit.exe at your Windows 2003 Server
• lookup the the key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\ServerLanguage] en put there a string value "1033"=""

You could also put the following into a fix.reg file using notepad:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\ServerLanguage]
"1033"=""

Thanks to Kevin Tunis :)
