Getting Custom.dic Location

[Neil]

I need to get the location of the custom.dic file on the user's machine.
Unfortunately, I'll be doing this from Access, and I'd prefer to not use
Automation, as that would create a delay while Word is opened. So......

1) Is there a way to determine the location of the custom.dic file without
opening Word?

2) If not, how would one access that information from within Word (using
Automation)?

Thanks!

Neil
