Updating CRM Version Error - System.Xml.XmlException Hexadecimal value 0x00 is a invalid character, line 1974, position 20

Posted on by yleclerc 1,545

We are trying to upgrade from 8.2.5.0004 to 8.2.6.0019.

We run the update. Then we try to update our oganizations, and a few seconds later, we get this error.

System.Xml.XmlException Hexadecimal value 0x00 is a invalid character, line 1974, position 20

Below is a small part of the crmdmsnapin.log file.

We are looking to find which XML file could be the problem.

Any help is much appreciated.

    It turns out we did have some corrupted XML files in the C:\Program Files\Microsoft Dynamics CRM\Setup folder.

    We ended up replacing those files with the ones from another server (that were uncorrupted).

    Then the update ran smoothly.

    Do you have any issues just opening the organizations?  How about creating a new organization, any issues there? Have you checked the web.config file?  Any further details in the Event Viewer on the server?
