When installing a new client PC from the data on the server I get the error:

Cannot Copy File QMapData.mdb

This is probably because the file QMapData.mdb may be missing off the server. This is caused by installing the server with Quickmap Version 4 (October 2004), then upgrading to Version 5 (October 2005). Then starting an install of the new client PC from the server which skips the Version 5 client upgrade step.

To fix the problem copy QMapData.mdb from the server AutoUpgrade\Release folder to the new client PC directory of C:\Program Files\QMap\Data.
