I installed Bugzilla with the handy Windows Installer (https://wiki.mozilla.org/Bugzilla:Win32InstallPackages)
I'm trying to upgrade to 3.6.3 following these instructions.
I've downloaded the tarball and get to step 18.104.22.168 but my webserver starts throwing 500 errors when I try to access the site. The apache error.log says:
The system cannot find the file specified. : couldn't spawn child process: C:/Program Files/Bugzilla/bugzilla/index.cgi
Is there something missing in those upgrade instructions?
