Hi,
my way to start Paradox is using a batch file:

1. setting some variables like work, priv, ...
2. setting some Registry Keys 
3. deleting old lock-files
4. start paradox with start-script

if you want to test it, just set the varialbes the way you want it ... 

may be, it might be interesting for somebody, may be somebody has some suggetions
.. 

batch File: startPdox.cmd
