Access Denied When Installing XP SP3

Had a client that had this problem. Found this on the internet.

Access Denied When Installing XP SP3

While installing Windows XP SP3, you receive the following error:

Windows XP Service Pack 3 installation failed.
Access is denied.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Resolution:

1. Backup the Registry

2. If subinacl.exe is not installed, download and install subinacl.exe.

3. Create a file called reset.cmd with Notepad. Copy the text below into the file reset.cmd and run reset.cmd from an account with administrative privileges:

Windows XP Home Edition:

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

Windows XP Professional:

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%\repair\secsetup.inf /db secsetup.sdb /verbose

4. Run windows update.

Windows XP SP3 should now install.
