Hi Carsten,

I'm using FB2 and FB1.5.3 on my laptop like this:
create some shortcuts on desktop with this command lines,
To switch to FB v1.5:
"C:\Program Files\Firebird\bin\instreg.exe" install
"C:\Program Files\Firebird\bin\fbserver.exe" -a
To switch to FB v2.0:
"C:\Program Files\FB2\bin\instreg.exe" install
"C:\Program Files\FB2\bin\fbserver.exe" -a

You know, you can see FB icon in try bar and
you can easly stop one and start other with some clicks.

You can also write batch files to do this operations.
Running them simultaneously on same PC may cause performance side
effects.

Regards.
Ali
