Thanks for the information. Well, that rules out my theory. We have different operating systems and software installed on our computer so that eliminates a compatibility problem. Also, only my 32-bit machine is affected. My 64-bit laptop has no permission issues with the registry.
I'm reluctant to tell you what I did since it only worked temporarily. However, look at the second post down in this thread...hamluis
(aka: "Louis") provided a link that basically gets to the root of the issue but it may or may not solve your problem.
Whatever causes programs not to work anymore for no apparent reason due to access control permissions remains a mystery.
Here's what I did (I cannot guarantee it will work for you, so do this at your own risk)
Download this small program
Install the program.
Now open Notepad and copy and paste the script below in the code box:
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
Go to File-Save and change the drop down box "Save as Type" to All Files (*.*)
Name the file reset.cmd
and save it to your desktop.
<Note: if you don't save it as All Files (*.*)
, you will end up with a text file named: reset.cmd.txt
. You don't want a plain text file.
1) Make a System Restore Point, name it something like: "Before Resetting permissions".
2) Double-click the file saved on your desktop. You will see a Command window open with a lot of writing scrolling down on the screen. Just let it go..it may take a while. When it's complete, the window will automatically close.
3) Reboot the computer.
Try Apple Software Update again.
If something went wrong or you get new problems, simply restore your computer to the restore point you made earlier to get where you started.NOTE:
If you find that any users are no longer shown on the Windows Login screen, let me know. They did NOT get deleted, there is a workaround.
