I have installed Windows Server 2012 R2 as a Hyper-V guest and the mouse will not capture when I open the remote window.

I have other guest OS running Windows 7, and they are all working.

With the Windows Server 2012 R2 guest, there are a number of unknown devices in device manager.

I have tried to run the integration services (IS) install, but it will not run as it thinks it is already installed.

I tried to uninstall IS using "Setup.exe /uninstall", but I get the same message saying it is already installed.

Hoping someone will have some suggestions for this.
