I installed version 2 on a slow laptop 455mhz P2 and it worked straight away after i installed the upgrade.
Go here for the upgrade.

By the way it is not a patch but an upgrade.
To get the program to work you first have to connect the camera and then start envisage or start dsi imaging from within autostar suite.
You can also use the camera from maxdslr if you have it.
Sometimes envisage can lock up and ypu have to close it and disconnect the camera and restart envisage after that.
Once it is running properly it will work ok.
