Products

• CA Spectrum

Issue/Introduction

Spectrum install or upgrade fails right after pre-installation stage. Pre-installation log doesn't show any error but there is SRAdmin SOCKET_ERROR error in Windows application log. If I run 'ipconfig /all' command I see Teredo IPv6 Tunneling configuration similar to the following:

If you ping the hostname, it gives the Teredo IPv6 address not the expected IPv4 address.

Windows Event Viewer shows the following SRAdmin error (Event ID=100)

SOCKET_ERROR: An existing connection was forcibly closed by the remote host.

If you stop Spectrum SRAdmin process and run the executable manually with --debug option and reproduce the problem the following message shows in the debug output

EMERG Error executing "E:/win32app/Spectrum\SS-Tools\lh_set.exe "E:/win32app/Spectrum\SS-Tools\lh_set.exe" "-q"". Create Process failed (1314): A required privilege is not help by the client.

EMERG SOCKET_ERROR: An existing connection was forcibly closed by the remote host.

Resolution

1. Open a command prompt with administrator privileges (Start->Accessories->right click on Command Prompt, choose Run as Administrator)
