We have a Visual Studio Installer which has many prerequisites one which is SQL Server Express 2008 R2 (English version)
We have a target computer which has SQL Server Express 2005 in Italian.
The installation fails with the error message as in this screenshot:
Is there a way to change the command line arguments to support a language independent upgrade?
UPDATE:
"Localized versions of SQL Server can only be upgraded to localized versions of the same language, and cannot be upgraded to the English-language version."

Does this mean the only way would be to backup data, uninstall 2005 and install the 2008 English version?
