i have the same problem with a popup on startup saying This version of Audio ESP is not intended for this operating system....my machine is a maxed out Dell OptiPlex 745 running win 10..i was one of those who were 'selected' to get the new win 10 downloaded n setup automatically a few hours before it was offered free to download to everyone..(still wondering why), anyway, of course once win 10 downloaded i had no sound drivers so..downloaded the sound driver from Dell's website..and all the 'recommendations' Dell's on-board program Dell Diagnostics, recommended...thats when this started popping up..everything else is copacetic...anyone else have this nuisance? & hopefully a fix for it?
