Keep your BizTalk Server up to date with the most recent cumulative update package for Biztalk Server 2006 R2 SP1. This package contains all of the Biztalk Server 2006 R2 hotfixes that have been released since the initial release of SP1.
Previous CU KB Articles:
The CU2 is only available in english, and the CU1 does not install correctly in the French BizTalk Enterpriese Edition Version.
Thank you Microsoft, selling product in different languages, and providing updates only in English... Super company !
Yes, the current CU model is English only. If you have an issue with a CU installing properly on a non-English system then you need to report the problem so that the CU can be patched. Usually if the problem is on the Microsoft side they do not charge you for the fix.
I wrote up a blog post with some relevant information on the CU release model: msinnovations.wordpress.com/.../new-biztalk-service-pack-model-cumulative-updates.
Read the "important notes about the cumulative update package" :
"BizTalk Server 2006 R2 hotfixes are now multilanguage. Therefore, there is only one cumulative hotfix package for all languages. "
