Thank you but when I open the DCS world it says
Please insert Disk 1 and click OK.
If the files on this disk can be found in a folder other than the one displayed below, enter the correct path or click Browse.
It gives me the path but when I click OK to continue it says-
The file "DCS_World_release_en_1.2.2.7570_69-1.bin" could not be located in "C:\Users\(myname)\Downloads". Please insert the correct disk or select another folder.
