我想问一下软件的license
Perpetual ownership
A Personal License can be used indefinitely, for the purchased version of the software. Upgrades are optional and provided pursuant to the IntelliJ IDEA maintenance terms. Each subsequent upgrade automatically terminates the rights for use of the previous versions.

最后一句话不是很明白，  

如果我的ide升级了， 电脑系统重装之后不会有影响吧？

我只要再把我购买的版本下载重新激活就行了？

------解决方案--------------------
就是说可以重装系统，放心吧
