Upgrading to BizTalk Server 2013 does not upgrade Enterprise SSO


When you perform an in-place upgrade from Microsoft BizTalk Server 2009 or BizTalk Server 2010 to BizTalk Server 2013, Enterprise Single Sign On (SSO) is not upgraded on the same computer.

If this issue results in the SSO Master Secret Server not being upgraded, attempts to upgrade other BizTalk servers in the group will fail, and you will receive the following error:

Please upgrade your master secret server

Also, any component of BizTalk Server that references Microsoft.BizTalk.Interop.SSOClient.dll can fail with the following error:

Could not load file or assembly ‘Microsoft.BizTalk.Interop.SSOClient, Version=7.0.2300.0


An in-place upgrade to Biztalk Server 2013 does not upgrade Enterprise Single Sign On (SSO) on the same computer.


To resolve this issue, manually upgrade Enterprise Single Sign On. To do this, follow these steps:
  1. Verify that the current master secret key is backed up to a secure location. 
  2. Verify that a current version of the SSO database is backed up to a secure location. 
  3. Run the Enterprise SSO Setup.exe file from the BizTalk Server 2013 installation media: 
    • For 32-bit computers, use the Setup.exe file at \Platform\SSO. 
    • For 64-bit computers, use the Setup.exe file at \Platform\SSO64. 
  4. In the Autorun dialog box, select Microsoft Enterprise Single Sign-On
  5. In the Summary dialog box, select Upgrade.

More Information

To determine the version of SSO on the computer, check the Server and Administration values at the following registry location. The correct value for a BizTalk Server 2013 environment is 9.0.1865.0.


The assembly Microsoft.BizTalk.Interop.SSOClient.dll file can also be used to verify the version of SSO. The default location for this assembly is C:\Program Files\Common Files\Enterprise Single Sign-On. In a correctly upgraded BizTalk 2013 environment, the file version will be 9.0.1865.0 and the .NET version will be 7.0.2300.0.
