Error 1603 occurs when installing Hotfix Rollup Pack2 on XenApp 6.0.
The Technical Support Engineer completed the following steps to resolve the issue:
Enabled msi logging and attempted the hotfix rollup pack install again. Error 1603 occurred.
Examined the msi logs; the following was observed:
CtxSetUserRights: SetAccountRights('ctx_cpuuser', 'SeDebugPrivilege') failed (1788) CtxSetUserRights: SetAccountRights('ctx_cpuuser', 'SeIncreaseBasePriorityPrivilege') failed (1788)
After examining the local user accounts on the server, it was found that there was no ctx_cpuuser account on the local machine.
To resolve the issue, create a local account named ctx_cpuuser. The Hotfix Rollup Pack will be installed successfully.
This error occurs because the installation is attempting to modify the rights on the ctx_cpuuser account. As the account does not exist, the installation failed.
