The Update Rollup 11 for CRM 2011 (KB2739504-V2) completed successfully. However, the database update failed for some organizations.

After installing the CRM 2011 Update Rollup 11 I’ve recieved a very interesting message:

The Update Rollup 11 for Microsoft Dynamics CRM Server (KB2739504-V2) completed successfully. However, the database update failed for some organizations.

After studying for a while, what I noticed was that:

• the default language for the CRM 2011 server was English (United States)
• the default language in SQL Server for the user used to do the installation was British

It seems that the difference between American English and British is so important that the CRM 2011 Rollup 11 cannot handle it :).

The SQL commands used to fix this were:

--Check the Language used by the CRM user
EXEC sp_helplogins 'user'

--See the language lists
SELECT * FROm syslanguages

--Update the SQL login configuration
EXEC sp_defaultlanguage 'user', 'us_english'

Then I have reaplied the update and it worked like a charm.
