Used configuration: Intel Core 2 Duo, 4GB RAM

I've installed Servoy 5.1.3. including Sybase SQL Anywhere Network Server Version on Windows7:
After the wizard, i run developer/servoy.exe;
The Windows7 firewall asked me whether i allow access to the public network, i clicked Allow Access.
Servoy freezes than with progress bar on ~33%
I tried to install it in:
c:\Servoy, c:\Program Files\Servoy, c:\Users\MyUsername\Documents\Servoy, e:\Projects\Servoy

How to setup OS for comfortable usage of Servoy with Sybase? Like it runs fine when i uncheck Database on installation wizard, because not all projects require Sybase.
Again: Servoy starts properly without Sybase, but unable to start Sybase at all.
