It's not. I would delete your post.
Yeah no cd patches are generally a violation of eula. Only example i know where it wasnt the case was in terms of r6 vegas 2 where ubi actually messed it up so bad they suggested downloading a patch off a torrent That went on for a while but then they came out with a fix and basically deleted everything they said about getting it
Uber stupid as it was said so people obviously knew so no matter how much they try to hide it its still out there
The ISO method should work fine. Another alternative that no one seems to have mentioned, is to use an external USB CD/DVD drive. See here: External-CD-DVD-Blu-Ray-Drives
They start at around $30.
It's funny because I use them so that I don't have to put the CD each time I want to play. Seems totally legit to me...
But I guess this is grey area, so I won't give any link to No-CD patches.
