After installing Mozilla 1.3, Mozilla can't find mozreg.dll. This file is not being installed.
hmmm. that's interesting because mozreg.dll is obsolete. What is the url that you got the mozilla 1.3 from? I can't reproduce this from the build found here: ftp://ftp.mozilla.org/pub/mozilla/releases/mozilla1.3
I've downloaded it from mozilla.org's releases page. $ md5sum mozilla-win32-1.3-installer.exe 9f67f2eb15feca6d5194ba167826fcf4 mozilla-win32-1.3-installer.exe We installed mozilla 1.2.1 and everything went fine. Even if there was some problem with a preexisting mozilla (I should check), Mozilla 1.2.1 had no problems at all.
please try to redownload and reinstall into a fresh *empty* folder.
