Windows XP Service Pack 3 (SP3) Setup Error: Access is denied.



As we all know Microsoft has released the final version of Windows XP SP3 to public and its available via Automatic Updates, Windows Updates and Downloads Center.

Earlier we posted about it at following link:

Windows XP SP3 RTM Available on Windows Update, Automatic Update and Download Center

You can download the SP3 from the above mentioned link.

A few ppl are facing a problem while installing SP3. Whenever they try to install it, Windows shows following error message:

Service Pack 3 setup error. Access is denied.

OR

Service Pack 3 setup error. Service Pack installation did not complete.

If you are also facing the same problem, then follow these simple steps and your problem should be solved:

1. Download and install the Subinacl.exe file from here.

2. Open Notepad and paste following code:

cd /d "%ProgramFiles%\Windows Resource Kits\Tools"
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

3. Save the file with name "SP3.bat".

4. Now right-click on the file and select "Run as administrator". It might take some time to complete.

5. After completion, restart your system and now you should be able to install SP3.

  • I wanted to uninstall SP3 (mistakenly installed by user) and when attempts were made to uninstall I was getting the Access Denied error. I installed Subinacl.exe and ran SP3.bat and I was able to uninstall SP3 with no problems.

    Very helpful...thanks.

  • Windows XP Pro - 8/13/2004 installed on Dell 8400

    Norton System Works 2008 - problems upgrading to the 2008 version. Customer Support finally got program installed on 3/11/08

    Attempted to upgrade to Adobe Illustrator Creative Suite #3 on 10/2/08 - Customer Service attempted to install but claimed that the Windows Installer was not working properly and concluded that the XP Pro system files were corrupted. They suggested a Repair Install to correct the problem.

    I have attempted the Repair Install several times. Sometimes the Repair booted from the CD states that it is unable to find a hard drive.
    I have attempted to install SP3 on the system. It fails to install with an error message access denied.
    I have a slipstreamed Disk with SP3 on it. It gets almost to the end with the access denied error message.
    I have attempted to unlock the registry files using Vishal's bat file and I get through about 2 million files and have 15 failures at which point the program ends. I am still unable to Repair Install or upgrade to SP3.

    I have even tried using Safe Mode. Still access denied error message.

    This is a single user sysytem. I am the administrator there are no other users.

    I took the precaution of making a second duplicate drive by creating a new boot hard drive and using the newly created, larger hard drive for all this experimentation.

    What's happening .... how do I fix it to either upgrade to SP3 or do the Repair Install.

    I dowload de subinacl file and then ran the SP3.bat it took for 3 hours to finish, then I restarted my laptop and then everything was messed up. And of course I can install SP3, it says there is an error.
    I prefer to not able to have the SP3 but have my laptop as it was, since it is a very important tool for my everyday work.

    Thank you very much for your help.

    ^^ If you have Windows XP setup CD, boot using it and then select Repair existing Windows installation. It'll take 20-30 minutes and will fix the problem.

  • Hey VG
    thank you for the tip. But I have been looking for the Windows Setup CD and I cant find it...I dowloaded one for floppy disks but my laptop doesnt have any Floppy Drive, is there somewhere I can dowload the Windows XP to repair mine? Coz my computer is getting worst, not only the drivers are not working, the main bar desappears after a while and the windows explorer open by itself.
    thanks again,

  • VG

    ^^ You can borrow the setup CD form your friend/relatives. The same disc will work on all systems.
