seems i am having better luck tonight. Got this one working too. downloaded dells ite cir driver for win 7 for my xps 1645. extracted files. ran installregistry.reg, rebooted. update drivers for unknown device with maching hardware id, search for updated drivers manually in folder where filers were extracted. Havent tested it with a remote yet but at least i could get the driver to install. They trick for this was the registry file. Without it i’d get the “driver isnt intended for this platform” under device properties.
Got it working, at least with motion in joy (I use it as a dedicated Bluetooth for my ps3 controller) I noticed i was getting side by side errors with the software via the event log. Some researching pointed out that I may need the proper visual c++ redistributable. Not sure which one specifically it was looking for so i downloaded and installed 2005 and 2008 x86 and x64 redistributables uninstalled and reinstalled the widcomm software and it is now recognizable by motion in joys ds3 tool. Whereas it wasnt before. I’d like to think with an unloading of the motion in joy drivers it would function as it normally should. Hope this helps some one else.
