All other programs on the disc work.
The install disk could be damaged, or if it is a "Sharpie" version, that may be where your problem is.
Should I have installed it to the program folder that was not the 64bit?
Not sure what you mean by this. You run the install CD, and it installs the programs in the right folder. 64 bit programs go under
C:\Program Files, and 32 bit programs go under
C:\Program Files (x86). Office 2003 is a 32 bit set of applications, so on a 64 bit system, therefore, MS Office 2003 goes in C:\Program Files (x86)\Microsoft Office\OFFICE11. If you install the proper way you don't get to choose to use (or not use) the program folder that is "not the 64 bit", whatever that is, so what did you do exactly?
