Currently have Unity 4.0.3 and Media Master worked fine on my desktop . Recently installed a new Unity 7 server and Media Master updated from 184.108.40.206 to 220.127.116.11 I would like to have the Media Master installed for the 4.0.3 version in this particular XP system. I have deleted the AvMediaMasterCtl Class from the Downloaded Program Files. When launching both the sa and PCA there is no prompt to install Media Master. I just get the lovely red X. When I open sa for the 7.0 system I am prompted to run the install however. Is there somehting else I can try to get this loaded?
