Hi Truefriend,
What is the update that you’re trying to add to your previous program and what program is it?
I would suggest you to try performing the steps mentioned in the link below.
The first step is to try using System File Checker Tool. If this did not fix the problem, then try performing a
system restore to the date when you were not getting this error message.

If the above steps fail to fix the issue, then try the following.
Let us try the steps mentioned below which involves system registry modification.
Note: Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications
of these settings are at your own risk. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

- Open the Start menu.
- In the white line (Start Search ) area, type regedit and press Enter.
- In regedit, go to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
NOTE: You can see the default paths for the user folders under the Data column.
- In the right pane, check to see if the missing personal user folder (under Name column) has the default
%USERPROFILE% location (under Data column) for it.
Note: The default location should be your C:drive.
- In the right pane, right click on the personal user folder that is missing and click on Modify.
- Type in the default location of the missing personal user folder, then click on OK.
NOTE: For example, %USERPROFILE%\Pictures.
- Close regedit.
- Log off and log on, or restart the computer to restore the folder.
NOTE : Sometimes you may need to restart more than once for the changes to be applied.
Now try to add the update to your program and check if you’re able to resolve the issue.
