How to install PDK6.6

Hi all,

I want to install PDK 6.6 but I dont really know how. I tried SystemAdministration -> Transport -> Import.... than Client as Source for the packages and it fails to add the .sda files. I tried also SDM...Deploy, choose the 2 sda files but when everything was finished I dont really know if anything happened in my portal..... I had a previous instalation of PDK 6.2, so the Java Role was already created...

Thank you very much for your help
