Always use the same user ID to apply maintenance with the Update Installer as you used to install the product initially.
In order to avoid problems, always use the same user ID for applying maintenance as you have for installing WebSphere Application Server, the Update Installer, and any fix packs. If you choose to use a different user then the maintenance action may or may not be successful depending on the ownership and permissions of the files to be updated.

The current operation must be performed by the same user who owns the existing files. Typically, the file owner is the user who performed the original installation. Switch to the right user, and then run the installer again.
