Introduction:
Installing Spectrum with user that is not the administrator is permitted, The user must have administrative privileges.
Question:
Can a user that is not the Administrator install Spectrum?
Environment:
Windows 2008r2
Windows 2012
Answer:

To install CA 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 CA Spectrum installation, the installation user is elevated to an administrator in CA Spectrum Remote Administration (SRAdmin). UAC would then need to prompt the user for permission, which is not possible because SRAdmin is a noninteractive service. Disablement of 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.
