Sure, first off, what exactly do you want to achieve? If you just want
to remotely access your VM (see the graphical desktop and interact with
it), you don't need the streaming agent for that, SPICE can do that for
a long time without it.

Streaming agent is designed for a very specific case of capturing and
encoding the desktop from within the guest, which only has an advantage
to the regular old SPICE approach if you have a physical GPU or a vGPU
assigned to the guest to accelerate the process.

If you still think streaming agent is what you need, please describe in
detail what is your use case.

Are you running Windows 7 as the guest? The streaming agent is designed
to run in the guest and only supports Linux atm.
