Windows surface pro 2.

Help
story so far I am using Ipad and everything is running so far and no problems.
A couple of weeks ago I bought myself Windows surface pro 2.

Hardware.
Free trial version
itach ip2ir.
Windows surface pro 2 operating system Windows8.1 and xbmc commander app installed.
Desktop PC operating system Windows 7 and xbmc installed.

This is what I'm trying to do.
On my desktop PC where I have xbmc installed I would like the surface 2 to open up desktop xbmc and then on surface 2 open up xbmc commander app. on the app I can control everything else I need to do Ie .volume. play. stop. and so on from there.
Problem is I can't get nothing to open from desktop no matter what application it is.

Example.
From desktop PC.

1.Execute."C:\Program Files (x86)\XBMC\XBMC.exe".
2.Execute.."C:\Program Files (x86)\XBMC"
3.Execute. "C:\Program Files (x86)\SUPERMICRO\IPMIView\IPMIView20.exe".
4.Execute. "C:\Program Files (x86)\iRidium mobile2\iRidium\iRidium.exe".
5.Execute. %windir%\system32\notepad.exe.
Am I missing something ?.

On Surface pro 2 I can get xbmc commander app to open.

Thanks Paul.
