Are WinRAR Licenses Perpetual or is There a Subscription?
WinRAR licenses are perpetual and valid for a lifetime.
You cannot register your license without purchasing it first, and WinRAR is not a free product. We offer all users a 40-day free trial, after which time the use of WinRAR without a valid license is in violation of our EULA.
Perpetual licenses mean that you can install and use your license for as long as you wish, but to stay up-to-date you must purchase a Support & Maintenance Package entitling you to all upgrades and updates within the 12-month period.
只买本体应该是可以永久使用当前版本，要一直更新使用最新版本的话是要 Support & Maintenance Package
