so your downloading one that someone else downloaded and extracted along with adding other files that are not part of the official r2r release. (media bay was not part of the r2r official release)

well the the path length limit as been about since windows 95 and cubase 13/14 r2r.txt says mount ISO so go figure.

if you lucky copy the cubase 15 folder to the root of one of you harddrives then rename the cubase15 folder to a single letter.. then try to install.
run as admin would normally be necessary for running a keygen.

if not you going to need to download the offical cubase 15 r2r release thats not been repacked and messed with by some random.
then mount the iso
