Uninstalling the Sigma Web Framework

The Sigma Framework is uninstalled via the "Add / Remove Programs" windows facility. The user navigates to this screen (via the Control Panel) and clicks on the "Sigma Framework" entry to execute the Uninstall program. The user follows the instructions of the dialog to uninstall the Sigma Framework system.

Note that, unlike most uninstall programs, the Sigma Framework files are left intact on the disk. Following the uninstall procedure, the user must physically remove these files, such as by dragging the Sigma root directory to the Microsoft Windows "Recycle Bin". This extra step safeguards any accidental removal of data on the system.

After running the uninstall procedure, but before manually removing the Sigma files manually, an administrator can re-execute the Sigma Installer program to re-install the registry keys other Sigma configuration components, as described previously.

Re-running the CO-install.exe program after uninstalling the Sigma framework will re-initialize the Apache password file, but will otherwise have no detrimental effect on the system. The administrator will be able to restore the password database by logging into the Sigma system, accessing the "System > Logins" screen, and regenerating the passwords by editing any entry or adding a new user.

In addition using the "Add / Remove Programs" facility, the user can execute the "Sigma\system\CO-uninst.exe" program manually. This has an identical effect to launching this program via the standard Windows "Add / Remove Programs" application.
