Snow Distribution 4.5 has many new functions both for deploying software and distributing through your Microsoft Active Directory. With Snow Distribution you can reuse all your existing MSI packages and distribute them much more flexible than you are used to.

With the built in packager you can configure the installation and distribution precisely for your needs. Snow Distribution now comes with both push and pull install technology and you have over 150 functions built especially for distribution and packaging purposes.

Snow Distribution is the most cost effective packaging and distribution tool on the market. Use your existing infrastructure without upgrades. Both the administratorÂ’s packager and multiple distribution points are free of charge. No expensive MSI-packager, no extra server and no database needed!
