After successes download Sabily Al-Quds, maybe you want to try it without install to you computer system that already installed with Windows OS. An easier way is to use virtual machine. Normally I'm using Virtualbox. You can download it from their homepage at http://virtualbox.org or directly from here (VirtualBox 3.2.10 for Windows hosts).
When your download finished, you have to install it to your Windows OS. Follow an instruction below to install it. For example I'm using Windows XP Service pack 3. I hope it was same to Windows 7 also.
01. Open your Virtualbox installation file.
Next we will setup a virtual drive for Sabily Al-Quds to be install on it. Hopefully you have reserve space on your hard drive for that.
