KB5046856 fails to install

  • Hello experts,

    The following SQL update is failing to install on some of our SQL Servers with the following error. Is anyone else seeing this? I've tried Googling the error but have not found a specific fix for this issue.

    Thanks for any help.

  • Thanks for posting your issue and hopefully someone will answer soon.

    This is an automated bump to increase visibility of your question.

  • The error is telling you what is wrong.  Also, if you go to the KB article, it will also tell you what is wrong.  It's saying that the instances where it's failing is because you don't have sp3 installed on some of your 2026 instances.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
