How can I install BugZilla? Before installing BugZilla, should I install Perl? If yes, which version of Perl for which version of BugZilla? And one more thing, my PC has 2GB RAM. Can you please tell me how to install it successfully?
Based on the information gathered, you can check the system requirements for BugZilla using the following page: https://www.bugzilla.org/requirements/
From what it says, 2 GB is a lot less than the minimum requirement.
The necessary version of Perl for Windows is: ActiveState Perl 5.12.4 and can be obtained from the following website: http://www.activestate.com/activeperl/downloads
You also need many Perl modules that can be installed with: ppm install modulename
