Sparki COM Port Connection Issues

I am using 30+ for a summer camp project and I am having connection issues. Sparki’s will (randomly) either:

-not be detected by the PC till I try 4+ different USB ports,

-OR they are detected but when the upload code button is hit they swap COM Ports.

I am using Windows 10 64bit 17.09 and the most current version of Sparki (
Of note: last summer we used Windows 7 with full patches and had the same issue.
