The 2007 Office suite Setup program will not restart after an initial installation is interrupted

Consider the following scenario. When you install a 2007 Microsoft Office suite or a 2007 Office program, the installation process is interrupted. Additionally, the Setup program is prevented from rolling back the 2007 Office installation. In this scenario, when you try to install the same 2007 Office suite or the 2007 Office program again, you receive the following error message:

This problem may occur if the Rgstrtn.lck file is not removed from the computer. If this file is present when you try to install the same 2007 Office suite or the 2007 Office program that you previously tried to install, the Setup program detects the file. Then, the Setup program stops the installation.

To work around this problem, delete the Rgstrtn.lck file. To do this, follow the steps, as appropriate for the operating system that you are using.
