Nick, I’m very sorry you are having issues with the installation and I hate to hear you don’t have install disks for Office.
Did it come with your PC?
I was skeptical that uninstalling alone would work because of all the files and registry entries Office leaves behind.
I think this solution might work for you.
1) Go to Add/Remove Programs and remove everything associated with MS Office. Reboot.
2) Download MS Office 2000/2003 Resource Kits. They are available on Microsoft’s website:

3) Run the 2003 Resource Kit. Use the Removal Wizard. Tell it to delete ALL PREVIOUS VERSIONS of MS Office. It will delete a list of files.
4) Next you need to manually delete the files that are still left behind. Delete these folders -
C:\Program Files\Microsoft Office
C:\Program Files\Common Files\Microsoft Shared\OFFICE11 (or "OFFICE")
C:\Documents and Settings\All Users\Application Data\Microsoft\OFFICE
5. Reboot and try to run Gain Master
Let me know what happens.
