Hi omarhomsi,
I've never heard of eGroupware myself. I checked out their requirements page and I see that for most of the products it says:
No client installation
That sounds to me that maybe you need to pay them to install it for you?
Do you have a copy of the software already? If so, I could help further with the installation process.
Most mysql / php driven programs can be installed following these steps:
Manual Installation of PHP Software
Feel free to post additional notes on the comments in this page, and we'll be more than happy to assist further!
Thanks,
- Brad
