xampp
Unfortunately, there is no full automated setup Wizard to install this software "with only a few clicks", at least at the time I could not find any. The installation process consists really of a lot of steps and requires some additional software on your computer, that's why, perhaps, it still doesn't have a compact installation wizard. One of the possible reasons could be that the database was installed and configured in the wrong way. I was trying to use SQLite, because it looks to be the easiest way and doesn't require any additional configuration but also faced a similar problem that I couldn't start my Bugzilla server. In general, I would like to suggest to use XAMPP. It is a bundle of software packages that are frequently used to run web applications. The name is an abbreviation to Crossplatform Apache MySQL/MariaDB PHP Perl, so it includes almost all you need to install and run Bugzilla. Just find some guide online how to install Bugzilla with XAMPP and try it. It is especially useful because this App allows you to start your Apache web server and your database only with a few clicks so after you just need to start your Bugzilla server and that's it
Using xampp with Windows 7 64 Bit
Xampp that I normally use for creating PHP-sites didn't worked at this computer with a 64 bit Windows 7. The Problem is that I needed it to make some changes in the source of a php-site and this with that new computer. First I had to install xampp which I did, but it didn't worked.
