Are you talking about the standalone player or the Web Player ?
WIN7 32-bit or 64-Bit ?
What EXACTLY do you mean by 'not working' ? That could be a thousand things.
Where on Google are you seeing the reports ? I did a search for 'Slingplayer WIN 7 problems' and the only suggestions seem to be the ones on this forum from a few months ago. Be interested to read the ones you say are 'all over Google'.
PS. All working beautifully on my 64-Bi WIN7 laptop
I understand that you are having some issues trying to get the SlingPlayer on a Windows 7 computer.
Unfortunately, you have not provided further details about the SlingPlayer version in use or the computer OS version. In this case, I recommend you to check the following link in order to get all the information about the supported Operating System and web browsers.
