You can use the -datapath command line qualifier for PowerSDR to specify 
where the database lives.  I have desktop shortcuts for various 
instances of PowerSDR, both Flex and HPSDR and keep the databases 
separate by using this mechanism.  For example, I have instances for the 
single and dual RX HPSDR flavors specified as shown below.  Note that 
this is on WinXP - the "appdata" syntax may be different on Windows 7. 
Note also there are no line breaks in each example (other than applied 
by my e-mail client).

-datapath:"%appdata%\FlexRadio Systems\PowerSDR_2232_RX1"

-datapath:"%appdata%\FlexRadio Systems\PowerSDR_2232_RX2"
