sp3 endless reboots fix?

[usergame]

Re-download SP3 from here and reinstall.

Tried to install in regular mode and safe mode with all peripherals unplugged but I get, "SP3 - ACCESS DENIED"

**edit - found this and will try it

1. Make a backup of your registry.

2. 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 with administrative rights (it may take a LONG time):

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

4. Reboot at SAFE MODE and try install SP3 again.



Good luck.
