The following is only applicable to Windows Vista.

As a result, you should see a folder called AccessChk on your desktop.

6. Type the following command, and press Enter:
accesschk.exe -s -n "nt service\trustedinstaller" -k "hklm\software\Microsoft\Windows\CurrentVersion\Component Based Servicing" >accesskchk.txt
Tip: You should be able to copy and paste the command into the command prompt.
7. Close the Command Prompt Window. Open the Accesschk folder on yoru desktop (if it has been closed).
8. Double click on Accesschk.txt (the text file), this should open Notepad.
If this does not help,

Note: About some driver update installation procedure, we also received this error code, please reroute this kind of case to Vista System Team, because, it may regard for third party programs structure.
Check for the updates after this.
