Issue/Introduction

Multiple issue while installing DX-Spectrum as User Account Control (UAC) was not disabled

Environment

Release : 10.x

Component : Spectrum Core / SpectroSERVER

OS: Windows

Cause

If you plan to install CA Spectrum as a user other than Administrator, turn off User Account Control (UAC).

Spectrum installation software requires administrator privileges to evaluate available resources and to run custom installation scripts. An initial installation generates residual files with administrator ownership. Subsequent upgrade installations also require administrator privileges.

Resolution

Follow these steps:
In a Run dialog, enter secpol.msc and click OK.
In the Local Security Policy window, select the Security Settings, Local Policies, Security Options folder.
Right click the "User Account Control: Run all administrators in Admin Approval Mode" policy, and select Properties.
Select Disabled, and click OK.
The necessary Local Security Policy option for turning off UAC has been disabled.

Note2: This policy setting controls the behavior of all User Account Control (UAC) policy settings for the computer. As you change this policy setting, you must restart your computer.
