Hi vAndrew,
nearly the same for me. I could install all services except the Update Manager. The is a an error 1603 in the logs and the setup is rolling back after the java runtime installation part of the setup, but could not find any helping information about that.
The hole vCenter-Server is totally slow after the update. The vCenter state is changing to red 2 or 3 time a day, sometimes i can't login. I run it on a proliant ml 350 g6 with windows 2008r2 server.
