Visual studio 2015 Visual Studio 2015启动时崩溃-可能与许可相关

我很抱歉，如果这是重复的-我已经搜索了相同的问题，但没有找到任何

我最近更新了VS 2015 professional SP 2，在此之后尝试打开VS会立即导致崩溃。我已将错误详细信息粘贴到下面

我尝试重新安装VS，运行带有各种/ResetSkipPkgs、/ResetSettings、/SafeMode标志的devenv，但行为并没有改变。我能够毫无问题地运行VS Ultimate 2013

异常详细信息（带有一些手动格式以便于阅读）：

如有任何协助，将不胜感激。感谢您抽出时间。

正在执行的

Microsoft Visual Studio Professional 2015及其更新

从控制面板>程序>程序和功能为我修复了这个问题
