我在 wpf 中使用了 Devexpress Grid。我想使用 ADO.Net 服务器模式将它绑定到数据库。我选择了“项目源向导”选项来执行此绑定，但它生成了以下异常：
InvalidOperationException: Cannot load Counter Name data because an invalid index '' was read from the registry.

Just had that message related to Microsoft Dynamics CRM updates not installing and the marked answer for this posthelped greatly:
刚刚收到与未安装 Microsoft Dynamics CRM 更新相关的消息，这篇文章的标记答案有很大帮助：
Click Start, type cmd right click cmd.exe, and select Run as administrator. At the prompt, type lodctr /rand press ENTER.
单击开始，键入 cmd 右键单击 cmd.exe，然后选择以管理员身份运行。在提示符下，键入lodctr /r并按 ENTER。
Apparently, Windows keeps some counters cache in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009\ Counter+Help. If this cache becomes corrupted (has blank lines), you get the above errors - and lodctr /rrebuilds that cache.
显然，Windows 在注册表中保留了一些计数器缓存在HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009\ Counter+ 处Help。如果此缓存损坏（有空行），则会出现上述错误 - 并lodctr /r重建该缓存。

Although this has already been answered, I see people are repeatedly getting the same error that I did when trying to solve it. If when you run:
尽管这已经得到了回答，但我看到人们在尝试解决它时反复遇到与我相同的错误。如果运行时：
C:\windows\system32> lodctr /r
C:\windows\system32> lodctr /r
you get the error
你得到错误
Error: Unable to rebuild performance counter setting from system backup store, error code is 2
Error: Unable to rebuild performance counter setting from system backup store, error code is 2
then you instead need to run
那么你需要运行
C:\windows\SysWOW64> lodctr /r
C:\windows\SysWOW64> lodctr /r
after which you should get
之后你应该得到
Info: Successfully rebuilt performance counter setting from system backup store
Info: Successfully rebuilt performance counter setting from system backup store
Note this has to be done as administrator. I found the solution here
请注意，这必须以管理员身份完成。我在这里找到了解决方案

Go to Start, type”cmd”.
Right-click on cmd.exe and choose ‘Run as administrator'.
Type “lodctr /r” and press enter.
转到开始，键入“cmd”。
右键单击 cmd.exe 并选择“以管理员身份运行”。
输入“lodctr /r”并按回车键。
You will then get the message ‘Info: Successfully rebuilt performance counter setting from system backup store'.
然后，您将收到消息“信息：已成功从系统备份存储重建性能计数器设置”。
Check if there are providers that are disabled, write “lodctr /q” and press enter
You will then get a long list of providers, make sure that the [CRM Client] is Enabled, see below
检查是否有禁用的提供程序，写入“lodctr /q”并按回车
然后您将获得一长串供应商列表，确保 [CRM Client] 已启用，见下文
If not, write “lodctr /e:CRM Client” and press enter.
如果没有，请输入“lodctr /e:CRM Client”并按回车键。
