When trying to install an App-V application, you get this error:
An error occurred when querying the App-V WMI provider.
Error Code: 0x87D01290
To fix error 0x87D01290, you need to reinstall App-V, repair WMI or the operating system. I suggest trying these fixes in that order.
This error is usually caused by WMI being broken on the PC you are trying to deploy the App-V application to.
