I have a valid license for the standard edition of ZCM, but when i click on the "system updates", it tells me there are no new updates, I have zcm installed and yet there is, so what could be the the pre-requirments to have system updates to run ? Or what should i check and to make sure it should work. I have checked the zcc.log, and tells the same message. The server has got internet connection through a proxy. And what else ?
