I have a older slingbox AV that works fine. I had to clean my windows 8 computer and was trying to download the software for the desktop and can not get it to complete installation. It gets to a point and says "unable to register SDK". At that point it rolls back the software. Can someone tell me how to complete the install or what I might be doing wrong? I downloaded it and tried running it as well as trying to run from install and get the same message. Your help is appreciated.
