    This ‘fix’ has been posted on MS forums (see & has only worked for a few people posting there, of which I am not one. Microsoft needs to acknowledge the problem & release a all-encompassing fix.

    The above “fix” never worked for me. I tried a number of things, and finally found something that worked.

    I have Win 8.1 64 bit version and was finally able to get the update to install after executing the following two commands in the command window with admin privileges (Win key + X, A):

    Dism /Online /Cleanup-Image /ScanHealth

    Dism /Online /Cleanup-Image /RestoreHealth

    The issue apparently was a corrupted file (“Amd64CNBJ2530.DPB” of prncacla.inf to be exact) that the above commands correct. Note no reboot was required after running the above two commands before installing the update.

    I had this issue aswell and none of the “fixes” in the post above or in the comments worked for me.
    I had to overwrite my win 8.1 installation with a fresh win 8.1 installation before i could finally update it.
    Something was clearly corrupted, but none of the repair methods worked.
