Vantage Patch 4.00.811

I have installed Vantage patch 4.00.811 and am attempting to run the schema
changes. The installation of the patch appeared install fine. I then
started the engines as indicated. I then went to our mapped drive
W:\vantage\schema change.vtg and double clicked on it. An error message
came up - The database W:\vantage\db\vantage is in use in multiuser mode.

What am I doing wrong?? Shouldn't I have started the engines (through
procontrol)? If anyone is out there please help!
