之前的项目需要老版本的1.9.3才能运行，但是安装的时候一直提示一个更新的版本已经安装在计算机上。然后也已经全部卸载了2.0.2。注册表也都卸载关了。但是重启安装还是提示有个更新的版本。。。。
有没有大神有遇到过这个问题？谢谢了
PS：雅鸡这个安装体验。。。 直接laya解压缩包多方便啊！！！
还有这个安装失败的log文件，求大神解毒

已经解决了。彻底卸载最新版是要重新运行的cocoscreator的安装程序，弹出界面，点删除就好了。直接应用卸载不行。
不能装多版本吗。。。
你的最新版本是不是装在了C盘，我试过 如果装在C盘，无法安装多个版本，都装在其他盘里 可以多个版本共存
可以安装的，重命名新的路径名称就可以。我windows上装了三个版本：1.9.3，2.0.2， 2.0.5
可以同时装在C盘共存，我装的三个版本都是在C盘

按照这个教程上面的办法，访问微软官方解决无法安装或卸载程序的帮助页，按照提示下载小工具并修复损坏的安装信息，即可继续安装旧版本了
