Can't launch in exclusive mode!

[Trek]

Hello there,

So recently while trying to use DS4 Windows in Exclusive mode I keep receiving the error that says I have Steam, Uplay etc open but I have closed down all and still error comes up. I have tried restarting PC and disabling all on start-up. Sill no joy. I have reinstalled and am using v1.45 with Windows 8.1. It's only a recent problem and is extremely frustrating. Any help would extremely appreciated.

Thanks,
Trek

Moving to the tools section, that's really the place for DS4 drivers
