问题描述

我尝试在PC上安装 Visual C#2010 Express版，但是每当我尝试运行它时，我都会收到一条错误消息.

I've tried to install Visual C# 2010 Express edition onto my PC, but whenever I try to run it, I get a error message.

无效的许可证数据.需要重新安装.

我已经尝试过重新安装它，消息仍然存在.

I've already tried reinstalling it, and the message persists.

OS是Vista Home Premium.我已经安装了VC# 2008 Express.

运行以下命令:
subinacl /subkeyreg HKEY_CLASSES_ROOT\Licenses /setowner=everyone
subinacl /subkeyreg HKEY_CLASSES_ROOT\Licenses /grant=everyone=f

Run these commands:
subinacl /subkeyreg HKEY_CLASSES_ROOT\Licenses /setowner=everyone
subinacl /subkeyreg HKEY_CLASSES_ROOT\Licenses /grant=everyone=f

再次启动VS 2010 Express，这一次它要求提供许可证密钥.

Start VS 2010 Express again and this time it asks for a license key.

(在Windows 7 Home上，我必须两次运行上述命令才能正常工作)

(On Windows 7 Home I had to run the above commands twice before they worked correctly)
