I am also having this problem. I'm pretty irritated as part of the reason I decided to go with another PC as my new laptop was because of this Intel Unison app. I have an iPhone and considered buying a Mac, but I am used to PCs and figured this app would be a decent substitute for AirDrop. My computer is brand new and says it's completely updated, and the Intel Unison app won't work because it says I don't have the correct Windows version (22621.0, while I also have 22000.1696).
Intel please fix this.
