Announcing Cumulative Update 9 for Microsoft Dynamics AX 2012 R3

Microsoft Dynamics AX 2012 R3 CU9 is now available to our customers for download on Lifecycle Services, CustomerSource and PartnerSource. Cumulative Update 9 build number is 6.3.2000.326. For installation instructions, download the Installation guide for cumulative update 9 for Microsoft Dynamics AX 2012 R3.

The newest changes can be found in the What's new in Microsoft Dynamics AX 2012 document found here.

For detailed information on Microsoft Dynamics Ax 2012 R3 CU9 release, please refer to the release notes official KB document KB3063879.

Please note, as happened for AX 2012 R3 CU8, the application version will show a different number of: 6.3.2000.323 if you apply CU9 to an existing install of Ax2012 R3.  This is due to all the granular models that are applied to your system through the CU9 install.  The one model indicating all models for CU9 has been applied has version number 6.3.2000.323.  Using a slipstream process as detailed in the Installation guide will result in the single full model applied for CU9 with build number 6.3.2000.326.

  12. Soren – please contact support with question on the license file being used – it seems to have an expired entry.

    When the VM 2012 R3 CU9 will be available on LCS ?

  17. Dich Guldberg Hansen says:

    I second Søren Printz Christensens comment above. I have used to axupdate from LCS to generate a package that should contain all relevant binaries. When I apply this package only a few choices have been checked off and none of them are related to EP, SSRS,
    SSAS, AOS, office addins or the AX client. How do we apply binaries to an existing environment, does anyone know.
    thought the LCS way of doing thsi was really cool and especially generating the install package was a very nice feature, but now its just not trustworthy, unless I am doing something very wrong here.
    Let me know what you Guys have experienced

    While compiling .net into framework CIL (CU 9 software update checklist) I get this error:
    CIL generation error : The given key was not present in the dictionary.

    This is the detailed error.
    Error when loading the method. Type: PayrollPayStatementTaxLine, Method: insert
    System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

    Any idea?

    I downloaded KB3063879 but when i select "Install updates (Select a previously downloaded update package)" I’m missing the .axupdate file that is required. Is this not the full update package and if yes where i can get it?

  23. Federico Riccio says:

    Martin Pfister you must download the slip stream from lifecycle services and put it in the updates directory of the original ISO
