I'm afraid yes. This way you'll not only avoid the 64bit-mess, but the 
language-mess too. At least on XP, %PROGRAMFILES% is different for every 
supported locale of XP. Vista and later kinda solved this by going a way 
similar to OSX (using localized paths in the gui but english underneath). 
If you want to stay compatible, c: is the easiest solution.

You could also go check the installer variables - maybe the installer 
exports a property for putting only the relevant datafiles somewhere else.

Or (finally) for your projects you could try SUBSTing the data to a drive 
letter - that way your SUBST-Script (that you should put in a login script 
or maybe a start script) is configurable, but the data is always at the 
same place. We do this for a few ancient software packages.

Best Regards
        Heiko
