Products

CA Spectrum DX NetOps

Issue/Introduction

During a CA Spectrum install on Windows, after the last configuration screen, a UAC error will show in the window noting you do not have proper permissions to run the install.

Errors occurred after providing account info with location to install software.

SPC-INT-20049 Insufficient Privileges on server to create registry entries.

SPC-INT-20050 Try using Administrator user for SRAdmin Authentication.

Environment

Spectrum install on Windows

Cause

The problem is even though you have disabled UAC from the User Account Control area, you have not actually disabled UAC until you edit the registry.

Resolution

Microsoft has created the following technical guideline to instruct users on how to actually disable UAC. Once you have disabled UAC and rebooted, you will then be able to successfully run the CA Spectrum installation.

Windows Server 2012: Deactivating UAC

Deactivating UAC in Windows 2008 R2 was possible via running msconfig (for example winkey+r -> msconfig), going to the Tools tab and launching "Change UAC settings".

There, you select "Never notify" to disable UAC.

The same approach is still available in Windows Server 2012, 20016, and 2019 though UAC is still active after you selected "Never notify".

Turn off UAC via registry by changing the DWORD "EnableLUA" from 1 to 0 in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system".

You will get a notification that a reboot is required. On some systems you do not need to reboot. You can log out and log back in and the install will run.

Additional Information

If you look in the installation logs, you may see access is denied errors:
