Welcome to Adobe Forum,
you can use the CC update patches (regularly maintained):
you have to manually manage the files and installations, as used to be the case (the old-fashioned way)... But if no other options are working or easily available to you, then there is a workable solution.
I would recommend reviewing Installation failed. Error U44M1P7 | Updates -http://helpx.adobe.com/creative-suite/kb/error-u44m1p7-installing-upda tes-ccm.html.
