RC3 Installation Problem

[vampire]

Good Morning,

I have tried to install the versions rc3 (10 Oct 2007 and 17 nov 2007) but, during the installation they always jam in different points. At times it jams in how much it doesn't read the pass of the MySQL inserted, besides, if I raise the pass MySQL to the database the installation it doesn't continue equally. To the moment I have installed with success the version rc2 (build: 2007-04-18). is possession possible a version rc3 with the sistem stable setup? Or to have the tabbelles for the rc2 upgrade to rc3, in how much I have effected the hand upgrade, as it did him in the preceding versions, but in the database of the version RC2s miss some present charts in the version RC3. is possession possible a guide or the db to add serving the update as the version rc2 to the version rc3, without rieffettuare the setup?

Thanks
