  1. Hi Melvin – when you extract the content the Binary content has .msis for both 32 and 64 bit.  The upload gets labeled with x86 but the .msis will be there in both the Binary only and full package.  

  2. @Aad – The cut-off dates for CU-4 and R2 were not the same, so there will be some hotfix content in CU-4 that is not shipped in R2.  

    @AxGuy – CU-4 is release for customers in the process of deploying or deployed on AX 2012 RTM.  CU-4 will enable these deployments to get the most current updates without having to install many hotfixes individually.  R2 has additional country functionality as well as feature updates.  In terms of the timing, we follow a periodic approach to shipping CUs.The window for shipping CU-4 happened to coincide with the window to ship R2.    

  3. Hi Mahmoud –

    Regarding the CustomerSource page I spoke with the support team today and the page is in the process of being updated with the CU-4 information.  The change may take a few days to cycle through and appear on the live site.  To find the specific items addressed in CU-4 you can visit the CU-4 page on CustomerSource.  There is a listing of the KB articles included in CU-4 that you can reference.  There is a link in the original post here if you click on the  KB2765124 hyperlink.

  4. Yes Bjorn – you are correct.  R2 will have separate CUs from AX 2012 RTM.  

  5. Hi Tommy – an in-place upgrade from CU-4 to R2 was tested successfully.

  6. Hi Normann –

    In terms of future support the difference in AX 2012 and AX 2012 are very small.  Each is serviced out of a different code branch, but each has the same product lifecycle in terms of end date:…/Default.aspx

    On the upgrade side of things we historically have enabled upgrade from the previous two versions.  

  7. Aad de Jonge says:

    Are all updates of CU4 also included in the R2 version?

  8. AxGuy says:

    I have the same question, why this CU4 is released at the same time than R2?

  9. Aad de Jonge says:

    Thnx Brian for the timely answer.

  10. Bjorn Kuijt says:

    I believe R2 will have it's own branch of CU's, is that correct?

  11. Tommy Skaue says:

    Could you please comment on whether or not an in-place upgrade to R2 is tested successfully from AX2012 RTM CU4?

  12. Tommy Skaue says:

    Thanks, Brian. I will be doing one tomorrow, so I would have discovered it sooner or later. Good to know it is supposed to work out. 😀

    Wish me luck!

  13. NormannRoedkjaer says:


    Is there any difference in future support if you choose not to install R2?

    Also keeping in mind AX7 upgrade, will it be possible to upgrade without R2?


  14. Mahmoud Dimassi says:

    Is there any reason CU4 is not listed in the customer source under the list of CU updates? I am in the manufacturing industry and i am hoping that CU4 will address some the performance issues that exists in CU3 and before.Also, whee do i find the list of hotfix's for CU4?

  15. Steven Hermans says:

    Is there a list of hotfixes that missed the R2 cut-off date? Will they be delivered anywhere soon?

  16. Melvin Barquero says:

    The hotfix appears only for x86… please let me know if we can use the same for 64 bit,


  17. Santiago Calle says:


    Im running the CU4 but im getting thousands of errors, is there any document about microsoft guidelines to set your AX2012 FP for applying the update correctly, when i run the CU4, it run ok but then when im compiling or sinchonizing or any after installation set up im getting too many errors… i will appreciate any documentation or info about this.
