Can not install office 2003 - Can not start office source engine

[Sarantsatsr]

Having a very short query, seeking for urgent solution. I am having a Windows 7 system with Two admin accounts (1 for me and another used by my bro). I installed Office 2003 that went smoothly without any problem. But while launching any office application, it gives a large error message as follows:

Error 25090. Office Setup encountered a problem with the Office Source Engine, system error: -2147024893. Please open C:\Program Files\Microsoft Office\Office11\1033\Setup.Chm and look for " Office Source Engine" for information on how to resolve this problem.

Zero percent idea to fix it. Can you guys suggest something ?

These error occurs when you tried installing Office on this pc with two different user accounts. I mean you tried installing Office twice. It may be your second admin as well. Anyways, in order to fix it you need to insert the Office 2003 installation disk cd/dvd drive. Double click Setup.exe from the root of the CD. As soon as the installation wizard appears, simply cancel it and respond to the prompts to exit Setup. Reboot the system and see if it helps you.
