Amy,

You are benefiting from the fact that I am solving this issue for a client right now.

I used to use the Windows Roku app, which apparently is no more (I still have it on my computer, and it works!).  So, there are three options that I am aware of, only one of which I feel is useable.

- Bluestacks - run Android on a PC

- Vysor - connect an Android device via cable or WiFi and run apps that way

- Logitech Harmony - then use Home Remote Windows software to control items.

My preferred option is the Logitech Harmony and Home Remote option - this is going to be the most robust way of doing it.  I also discovered last weekend - as I have a client with a Roku right now that I am trying to control - you can actually customize the layout of Home Remote, if you need to.  The good thing about the Roku is that there are not a lot of buttons so most users would not need any customization.

This does assume that this is a Roku box or stick that uses RF controls.  If it is a Roku TV, then it is all IR.  FYI, I recommend Roku TVs all the time because the remote is so simple!
