Had the same problem with .NET framework 4.5.1 update; after trying all suggested solutions (use the System Readiness Tool, use the .NET repair tool, use the .NET Cleanup / uninstall tool) without success, the problem turned out to be that the C:\ProgramData\Microsoft\NetFramework directory didn't have the right permissions to be able to be written to BY THE INSTALLER WHICH CREATED IT. An idiotic error, to be sure. I simply created the directory myself and set the permissions on all C:\ProgramData directories to "SYSTEM: Full Control", "Administrators: Full Control" and "CREATOR OWNER: Full Control." The next time I tried the update it worked perfectly.

Hi Auriam, sorry for the bump, but what do you do, you copy all Programdata info to new folder, delete the old one (how?) and rename the new one as programdata?
