Hi, i use a ultimaker 3+ and Cura. But when i install cura 2.xx in a win 10 pc i have this problem:

Disk not present

Impossible to find the disk in the unit. Insert a disk in unit D:

D: is my dvd reader, but i didn't intalled cura in this position but in C:\Program Files\Cura 2.6.

Also I can't close the error window, but i have to crash cura and then i can close the error window.

I use another pc for print.
