Commerce Server 2007 Service Pack 2 does not install successfully

When you try to install Microsoft Commerce Server 2007 Service Pack 2 (SP2), the installation is not successful. Additionally, any Commerce Server 2007 SP2 changes that may have been installed are backed out.

This problem occurs because of a problem with the MSI Installer program when certain Microsoft Commerce Server 2007 Service Pack 1 (SP1) hotfixes have been previously installed.

To work around this problem, remove all Commerce Server 2007 SP1 hotfixes before you install Commerce Server 2007 SP2.

4. In the Currently installed programs and updates list, click a hotfix for Commerce Server 2007 SP1, and then click Remove. Repeat this step until you have removed all Commerce Server 2007 hotfixes.
