This can be useful to fight the error but you will have to edit the registry in order to change it. You will also have to continue installing programs in the old Program Files folder, at least until you process the update which is causing this error.

Solution 3: Make Sure You Have Enough Disk Space
This error is more aimed at users who receive the error when trying to update using the Windows Media ISO tool. Even though the setup may seem small in size, you will still need as much space as you can gather in order for the process to finish without problems. We suggest you clear out as much space as you can, either manually or by using a tool which can get rid of unused files on your disk. Pay extra attention to programs and applications you no longer use as they tend to take up the most space on your disk.
Solution 4: Reset Windows Update Components

It’s a brute way to force the Windows Update service to reset itself but it’s definitely one of the most useful things you can do in order to fix the broken Windows update service. The only reason why we have chosen to put it at the last place is because the methods above are shorter to do for users and they are more specific to the error code whereas this method is lengthy, more complicated, and also more general.
