installing downloaded software

On most mac programs you sinply have to open a .dmg image and then drag the app to your application folder but, in this case, you must use Adobe's Setup application; you can't simply drag a folder to your hard disk on the Mac, as is now the standard method of installation. In other words, this is like a window application install where you doubleckick the eecutible icon and then follow the onscreen prompts culminating in a" gasp" system reboot but the bad news is that you appear to have a machine that is not compatible. PowerPC® G4 or G5 or multicore Intel® processor
Mac OS X v.10.4.8
512MB of RAM
1.4GB of available hard-disk space (additional free space required during installation)
1,024x768 monitor resolution with 16-bit video card
DVD-ROM drive
Internet or phone connection required for product activation
Broadband Internet connection required for Adobe Stock Photos* and other services
Just from what little information you have given you are short in one area and may be short in another.
You have got to own a Mac that you can upgrade to 10.4.8 so your machine has to support Tiger.
Secondly, they are saying you must have a dual cpu board. It is clear you must be running a PPC chip so if your machine is say an 800 mhz it must be a dual 800. I am, though, guessing that your machine is a g4. But, even if you  can successfully upgrade two os versions, you may still not end up with a machine that will run this app. Now I suspect that it may still install in a single core proecessor with 10.4.8 but will just be dog slow, however, I  have not yet found anything to confirm or deny that.

Actually, never mind about the dual core part of the above post I misread it. It will install with a single core g4. But, having gone to the forums to double check it I found numerous complaints about exessive cpu usuage and slooooow functions on machines that I suspect are much faster than yours. I greatly suspect that you will need a much newer machine than what you have to run this app without aging visibly in front of the screen.

Thanks I read on Adobe something that confuised me. Can I put dreamweraver on 10.2.8 or must I upgrade to a newer SW? If so do you know if I can go to the latest or will I have to do steps?
