Not sure what this means, but the techs at Best Buy (where I bought my
Toshiba) couldn't uninstall the Office 2007 trial either. They suggested I
search for an "uninstall.exe" file somewhere in my Office 2007 program files
folder to attempt an uninstall from that. I haven't found that file yet!
If that doesn't work, these particular techs said that it should not be a
problem to install Office 2003 without uninstalling 2007. I haven't done
that yet, but I only have two thoughts to go along with it:
1. Make sure you install to a different folder than just plain "Microsoft
Office" (which is probably the default install location). Create a new
folder during the install process (when the screen prompts you for the
location to install to) called "Microsoft Office 2003" or "Office 03" or
something like that. Hopefully, that will keep all 2007 and 2003 files
separate and untangled.
2. After you install 2003, make sure the Office file types (.doc, .docx,
..xls, .xlsx, .ppt, .pptx, and so on) are associated with 2003 by default.
If you don't change that in the default program settings, your computer may
continue try to open them with the expired 2007.
If I discover something different when I've completed this, I'll try to
remember to post again and let you know.
