Hi nomishtam, It seems that you have requested support for a localized product. Since we do not familiar with this language, it is very difficult for us to perform further troubleshooting steps, such as capture the log file. These forums are geared to answer on the English version of the product. I would suggest you seek the solution in the following forum, thanks: http://social.technet.microsoft.com/Forums/fr-FR/1109/threads If you have any feedback on our support, please click here Frank Wang TechNet Community Support

I just got this in English. Repeated twice; the 2nd one said "An unexpected error has occurred and a Watson dump is being generated....." Where can I find and then send the dump? This was after two previous attempts at upgrading Exchange 2013 to CU1; I fixed the two previous errors, rebooted, and hit this on the third run of the CU1 setup. This happened on "Step 7 of 15: Mailbox role: Transport service"

Solved: Disabled all IPv6 components via reg key (FixIt not available), rebooted, and restarted CU1 install.
