My hard drive failed and a new hard drive has been installed on my iMac. I now have to reinstall Photoshop CS5. This is an upgrade version but I have the full version of CS3. I can't get the installation disk to run from the DVD drive (I have installed other software from the drive today so this is not faulty). The disk is simply ejected. I am using OSX Lion. What am I doing wrong?
Try copying the contents from the PS dvd to the desktop and try installing it.
If still same issue with the dvd drive, then you might want to copy it to any other machine that has a working dvd drive and then transfer those files to a USB drive and try to install PS CS6.
Thank you Arpit. I have discovered that the fault is with the optical drive and had to be replaced as it would read cds but not dvds.
