<div id="ygrps-yiv-1832469620">I have installed Vantage patch 4.00.811 and am attempting to run the schema<br/>
changes.  The installation of the patch appeared install fine.  I then<br/>
started the engines as indicated.  I then went to our mapped drive<br/>
W:&#92;vantage&#92;schema change.vtg and double clicked on it.  An error message<br/>
came up  - The database W:&#92;vantage&#92;db&#92;vantage is in use in multiuser mode.  <br/>
<br/>
What am I doing wrong??  Shouldn&#39;t I have started the engines (through<br/>
procontrol)?  If anyone is out there please help!<br/>
