Do a search on the forum for the plug-in problem, there are lots of posts about it, I just can't remember the answer. To install the BIN files use How to Install a Custom Remote onto the Slingbox – Place Shifting Enthusiasts
You need to have a browser with the plugin to use setup.slingbox.com.
Using both sets of .bin files; Cisco DTA170 and Cisco DTA250HD I get a consistent "Remote code is not valid. Please try a different code." from Slingplayer for Windows Desktop 2.0. Is there a difference between the codes that work with the legacy Sllingplayer 2.0 and setup.slingbox.com?
OS; Windows 7 Ultimate (x86)/32-bit
Browsers lasted Chrome and Firefox
Cox Minibox / Cisco DTA250HD.
The installation instructions do not work from a browser install as I get a plug in not support error using Chrome as I can't get to setup.slingbox.com to begin with. From Firefox I get a corrupt plug-in error.
I have tried using the legacy Slingplayer 2.0 for Windows and putting the remote files in the SBAV folder. I get an remote .bin file error.
