I may have made an error in judgment by asking this question again, but
having played around with it, I can state the concern properly...

I have created a worksheet which has to run on various user's PC's. It takes
two Do Not Call List area code files, joins them, reformats the data and
then determines if any if the data is also found in data from a reverse
telephone directory, and creates a list of numbers that can be called.

The three data files used are downloaded from the Internet, onto the user's
Desktop. My Excel spreadsheet needs to open the files. The users typically
have Windows 7 or Vista.

I've been told that I can access these files with
Workbooks.Open Filename:="..\Desktop\XXX.csv"

This works on Windows 7 machines, but not on Vista - the only difference in
the software used.

Is there a simple way to fix this?
