Performing the Pre-installation Procedure
Before you install WebSphere, you must first set up a local user account that is in the Administrative group and has these advanced user rights:
Act as part of operating system
Create a token object.
Log on as a service
Replace a process level token
To set up a local user account with the above user rights, navigate to:
Control Panel > Administrative Tools > Local Security Policy > Local
Policies > Users Rights Assignment
On User Rights Assignment, double-click one of the user rights, click Add, select a local user account from the list, and click OK. Repeat this process for the remaining user rights.
