Being a registered user of one or more Coolmuster products, you are entitled to a free copy of any updates for most of products. As long as you have purchased Coolmuster products, you can get free life-time upgrades for most of our products as you like. For example, if you have got Coolmuster PDF Converter Pro, you can upgrade the Coolmuster PDF Converter Pro to the latest version as long as the newest one is available, but if you purchase the Coolmuster Android Assistant with "1 Year Subscription", then you only enjoy the free upgrade service within the valid time.
A major upgrade is released with a significant amount of improvements and new features, and the first digit of the version number changes. If the update is not free, we will send out a newsletter to our registered customers, who can then enjoy the major upgrade by paying only a small upgrade fee.
