Recently we changed installers to do a selfcheck at the beginning of the installation.
Therefore the MD5 checksum topic, provided on forum will match only for the installers without selfintegrity check.
MD5 checksum topic will remain on forum for those who own previous installers.
So - if your installer finished their selfintegrity check without telling you that it's corrupted, then you don't have to bother for checking the MD5 checksum by yourself.
