This article applies to:

• MailMarshal SEG
• Upgrading an installation
• Automatically upgrading a node from the Array Manager

Symptoms:

• Upgrade fails
• Error message: Error opening MailMarshal SEG registry key. Failed to query value 'CurrentConfig', 2
• Running Windows Programs and Features shows the message: There is a problem removing this software. Would you like to remove it from the list?

Cause:

This error on upgrade can be caused by the removal of the InstallShield directory which stores the data about previous installations (by default, C:\Program Files (x86)\InstallShield Installation Information), or the SEG specific subdirectory in this directory.

"System cleanup" applications might remove this directory or you might have removed it by mistake.

Solution:

Run the installer for the exact version of SEG that is already installed (such as 8.0.4.10434), and "install" it with the same options and modules. This process will re-create the uninstall information. After completing this process, you will be able to upgrade.

Notes:

• Removal of the InstallShield directory does not affect SEG functionality.
• Re-installing does not affect existing logs, quarantine folders, or any other files that were changed since the previous installation.
