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:

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.

  • Unbelievable! I was so frustrated and you made it so easy. The fix worked perfectly after several failed attempts with the Microsoft fix suggestions. I have the Media Center Edition of Windows XP Home. Thank you so much VG!!!

  • VG,

    I was wondering if there is a work around for having admin access to get SP3 installed on a network of computers. We are not running SMS so here lies the issue. Users do not have admin access for the SP3 to update. The genuine advantage update has to run first before the SP3 can run.

    Is there a way to create a script for users to be able to click on......rather than get the update from M$ I want the workstations to get the source from our server. Any suggestions?
