Hi @razvan_iacob,
You should replace $BASE_DIR/apps/studio/$HTML5_STUDIO_VER/studio.ini and $KMC_PATH/config.ini with the actual paths to your versions, in my case:
/opt/kaltura/apps/studio/v2.0.8/studio.ini
/opt/kaltura/web/flash/kmc/v5.41.2/config.ini
But you will have different versions since you're not running on the latest [12.8.0].
