Hello Everyone,
This issue has been resolved,

here is another tool for your toolkit. SP2 finnaly installed as well as 44 addtional updates, I was even able to install Norton AV 2006 which previously failed on account of the same issue.
Here is the reply I got back from Microsoft , they replied in 24 hours. It was evidently a problem with permissions being denied to write to certain folders and in the registry. I am attaching the file for anyone that wants to download and keep it for future problems.
Dear Ken,
Thank you for contacting Microsoft Online Support Service. My name is Andy, and I am glad to work with you. For your reference, the case ID for this service request is You can contact me directly by writing an email to [removed] with the case ID in the subject line.
From your description, I understand that when installing Service Pack 2 (SP2), an error message "Access Denied" is received.
If I have misunderstood your concern, please do not hesitate to let me know.
I understand the inconvenience this issue has caused. Please be assured that I will try my best to assist you in resolving this issue.
Generally, this type of installation issue can occur if the current user account does not have the correct permissions to access related folders and registry keys. I suggest we first perform the following steps to install Windows XP SP2. If the issue also occurs, I will continue working closely with you to resolve the issue.
I suggest we first try the steps below to reset the default permission on those folders and registry keys, which will be accessed when installing SP2:
1. Save the attachment of the email to your Desktop.
2. Right click on the "Reset_subinacl.ZIP file" and choose "Extract"
3. Follow the instructions to extract the files to your Desktop. There will be two files (reset.cmd and subinacl.exe) extracted.
4. Double click the reset.cmd file
5. You will see a DOS-like window processing.
(Note: It may take several minutes, please be patient. When it is finished, you will receive a message stating "Finished, press any key to continue".)
After the above steps are finished, please, download the full installation package of Service Pack 2 from the following website and save it to C:\ (The root folder of partition C):
http://www.microsoft.com/downloads/details…&displaylang;=en
Next, restart the computer in Safe Mode using the following steps to have a stable environment to install SP2:
1. Restart the computer.
2. Keep pressing the F8 key until the Windows Startup menu appears.
3. Choose Safe Mode, and press Enter.
(Note: In Safe Mode, your system display and Desktop will look and perform differently than in Normal Mode. This is only temporary. To return the system back to Normal Mode, we can simply restart the computer.)
Go to C:\ to find the full installation package file, which you just downloaded, and then double click the file to initialize the installation.
