Environment

Release: Any

Cause

User Account Control (UAC) component is turned 'on' on the Windows system.

Resolution

To solve this problem turn off the UAC component on the Windows server where NetOps Spectrum is being installed.

Details are provided in the following section of the NetOps Spectrum documentation

User Account Control (UAC)

To install DX NetOps Spectrum as a user other than Administrator, User Account Control (UAC) must be turned off. UAC is a Windows security component that prompts you for permission when a task requires administrator privileges.
During DX NetOps Spectrum installation, the installation user is elevated to an administrator in DX NetOps Spectrum Remote Administration (SRAdmin). UAC would then need to prompt the user for permission, which is not possible because SRAdmin is a non-interactive service. Disabling UAC allows the installation to run continuously.

Note:
Disabling UAC is required for CA Spectrum installation as a user other than Administrator only. After installation and during normal CA Spectrum operation, UAC can be enabled
