StarWind Software

starwind 4.0 build is expired 14 days. i dont have any option to buy the software currenlty. how can I use the same soft ware for more 14 days.

uninstall & reinstall will work here? will that effect my current cluter configuration???

Dump V4.0 (it's more then 5 years old, no idea where you've managed to find it...) and use the most current V5.8 (Free version if you're fine with features and support for it).
