2. Installation and activation

To install the VEGA ZZ package, you must execute Vega_XX_Win32.exe file following the simple installation wizard. If your operating system is Windows NT 4, Windows 2000, Windows XP, Windows Server 2003, you must have the administrator rights.
If your system has got a software firewall, you must configure it granting the network access to REBOL.exe, otherwise the scripting system doesn't work because it uses the standard TCP/IP communication ports.
After the installation, run VEGA ZZ to begin the activation procedure needed to unlock the software. The activation is totally FREE:

Follow the procedure reported in the window:

Please remember that the activation key is generated starting from the product key. The product and the activation keys are personal and they work with a specific PC/workstation only. You can't activate more than one PCs with the same activation key because each PC has a different and unique product key. The activation expires after 1 year for non-profit academic users and after 30 days for business companies. After this time it's possible to request another activation key. The two activation types can be selected during the registration procedure. The Authors can change the licensing method in any time on their own decision. The business companies can't access to the collaborative support without purchasing the Support Pack (available requesting to the Authors): help or new feature requests will be trashed if they are from companies without Support Pack. The Authors spent a lot of time to develop a software that, in some cases, includes better performances than several commercial packages. We request a little contribution to the companies in order to continue the VEGA ZZ project otherwise destined to end in the near future.

 

2.1 Installation of optional components

The optional components require VEGA ZZ pre-installed on your PC. Some of them aren't included because they may be not useful for everybody and/or require a separate license agreement.

 

2.1.1 VEGA ZZ Live CD Creator

VEGA ZZ Live CD Creator is a software developed to create live distributions starting from the VEGA ZZ files installed in your PC.

2.1.2 Mopac2007 and Mopac2009 installation

The VEGA ZZ package includes Mopac 7.01-4 for the semi-empirical calculation, but it's possible to use the latest Mopac 2009 that if correctly installed, is automatically detected by VEGA ZZ. For copyright reasons, Mopac2009 isn't included in the package but it can be obtained at http://openmopac.net.
Please follow these steps for a correct installation:

WARNING:
If you install both Mopac 2007 and Mopac 2009, VEGA ZZ gives the priority to the newest one and so Mopac 2009 will be used.
