Forget it. It's hopelessly outdated and doesn't run on contemporary operating systems. You need to buy a current version of Acrobat.
Moving this discussion to the Adobe Reader forum.
If your iMac doesn't have a CD, Adobe reader or Acrobat are the least of your worries. Since they ALL have built in CD or DVD drives, I can only assume the "no CD reader" means the drive is no longer working.
That means that inevitably, you'll start seeing the "grey screen of death" or a Kernel Panic error caused by bad hardware.
Enjoy this iMac while you can... its days are numbered.
"Since they ALL have built in CD or DVD drives, I can only assume the "no CD reader" means the drive is no longer working"
- do not think you are correct. All contemporary iMAC's dont have CD drive at all. Of course, I can buy external drive and connect it through USB - but there is no internal drive in iMAC.
Anyway, thank you for the help attempt - Emanuil
Okay then I'm lost again... If this is a new iMac (the last one I bought new was in 2005 and it had a DVD Superdrive - it was a 1st generation G5 and it burned up [literally] in three years. I haven't looked at an iMac since.) Why on earth are you looking to put years-old software (Reader 5.0 was released in 2001 and built for PPC and not compatible with an Intel system that DOESN'T have Classic environment) on it?
