Can't export Outlook contacts to CSV file

I'm using Office 2003 on a Windows Vista computer. This morning I tried
to export my contacts to a Windows CSV file and I got the message that the
translator needed to produce the file was not installed and asked if I
wanted to install it. Of course I said "yes" and the instllation of the
translator appeared to start. A few seconds later another message appeared
saying that file SKU111.cab couldn't be found. I was prompted to provide the
installation CD for Office so I did that. Even though the missing file is
on the CD the instllation file refuses to do anything with it. I highlight
the file L:\SKU111.cab (my cd drive is L) and click OK the window flashes and
goes back to the same browser screen asking for the location of the
cabinet file.

Can anyone shed some light on this problem?

Thanks,
Cec Britton
