SOLVED: Adobe Error 1328: Error applying patch to file

Adobe Acrobat updates may fail with:

Error 1328: Error applying patch to file C:\Config.MSI\PT3E87.TMP.  It has probably been updated by other means and can no longer be modified by this patch. Adobe-Error-1328-Error-applying-patch-to-file-c-config-msi

While I still have no verified explanation for this error, I have seen it enough times to figure out a work around which can be summarized by saying install the patches manual:

  1. Go to the Adobe Updates page
  2. Scroll through the page until you find your product, then click on the most current patch
  3. Download the .MSP and install it
    1. Note that if you see your patch ending with the letters …INCR.MSP that is an INCREMENTAL patch and you need to the previous full patch before installing that one.
  4. When prompted with¬†Error 1328: Error applying patch… click the IGNORE button

    This is the actual solution. All the other “solutions” do not work.

    After deleting that folder, the installation completed successfully. ”68AB67CA7DA73301B744CAF070E41400”
