1.- Create a folder and name it "Disk1" (without the quotes)
2.- Copy the content of your DVD to that folder except files Data12.cab and Data13.cab
3.- Download the "
DEVIL MAY CRY 4.msi" - it's in RAR so you must extract it to the Disk1 folder overwriting the one you have there.
4.- Burn that folder (remember: the DVD label must be "Disk1")
5.- Create a folder and name it "Disk2" (without the quotes)
6.- Copy the files Data12.cab and Data13.cab to that folder
7.- Burn that folder (remember: the DVD label must be "Disk2")
Done!
The install sequence will be Disk1, Disk2, Disk1.
