I have a small vmview set up with 7 vm's. I updated one view agent a few months back from 5.1 to 5.2. I am now trying to upgrade the rest to solve a usb redirection error but it will not allow it. Starts the install process but then half way through it just rolls back and fails. Tried uninstalling the agent first but that fails too? Look in the event logs and can see nothing but an install fail error.
