Popup error won't go away

[brettr]

I'm running Netscape 4.7. I just reinstall after formatting my HD and get a
popup error message about can't find temporary file on C:.  It says to set
this in the preferences box.  There is no preferences box. The popup occurs
each time I start Netscape.

I did go into the Netscape preferences but don't see anything references a
temporary directory or folder. Where should I look and for what?

Thanks,
