ty , but how can i upgrade or add those  features to my router in packet tracer?

Use GNS3 instead of PK you will get all functions for multicast igmp and pim both work fully

change image in PK

It is possible to upgrade the IOS of a device in Cisco Packet Tracer.

1. Put the TFTP server into the workspace
2. Click on it to open its properties
3. Go to the Config tab, then click TFTP. This will show you different IOS versions which can be downloaded on a router or switch device.

So best way is to find that out yourself as in real world you will have to eventually , there is a tool cisco feature navigator that you use for this you can search by software and see what features are available  ---http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

Saying that , that image is an advanced ip services image it does support multicast I would be almost certain of that , I would say the issue is Cisco may have it blocked in PK , are you sure its supported as not all features are and that's why a lot of people use GNS3 or IOU for virtual labbing as there full images

Just to show how it works your image does support PIM so Id say Cisco have not allowed it for some reason it even supports ipv6 pim ,and advanced ip image will usually have nearly every ip feature running ,  see attached screenshot from SN
