Having trouble getting Office '03 to work with Vista. I burned all the files on a CD-R from my old computer and tried uploading them on my new computer. When I try and start Excel it says that the OS is not presently configured to run the app. I tried installing a converter and then hasn't resolved the situation. I think I might be trying to install the wrong converter. Not very tech savvy...anybody know for sure the converter that I need for this?
