SYMPTOMS
When you attempt to install Service Pack 4 for Windows NT 4.0, you may receive the following error message:

Service Pack Setup Error. You do not have permission to update Windows

NT. Please contact your system administrator.



CAUSE
This behavior can occur if you run the Update.exe file from a folder other than the Update folder. The Update.exe file must be run from the Update folder.



RESOLUTION
To resolve this issue, run the Update.exe file from the Update folder.

The affected files are Update.exe and Update.inf. These files must be in the Update folder or the error messages will occur.



MORE INFORMATION
The Update folder is located in the folder to which you extracted the Service Pack files, and contains the following files:

Update.exe

Update.inf

Update.nvt

This error only applies when the registry's RunOnce key is used to run a batch file.

The batch file maps a network drive back to a server location where the Service Pack 4 files are located (not under the $oem$ directory on the distribution server) and then runs Update.exe. For more information concerning deployment configurations, see the "Guide to Automating Windows NT Setup" deployment guide located under Deployment Tools at the following Web site:

http://www.microsoft.com/ntworkstation/

The other method most commonly used is to run the Update.exe program from the Cmdlines.txt file. This will not work with Service Pack 4 because it contains long file names that would be truncated during the text mode copy phase of setup.
