I would like to let you know that I manage to convince my hosting provider to create auto installer of Open Cats. Now it takes 35 seconds to have full install . Unfortunately for you the hosting company is based not in the native English speaking country. But this has no influence on OC and the quality. There are many other auto installers like: OrangeHRM, Moodle, eFront, LimeSurvey etc.
If you are interested just PM me.
Greetings for all enthusiasts of OpenCats
