Try copying the installation files into a temporary folder on the hard drive and installing from there.
If you get the same error, try copying the whole thing again to the USB drive. Be sure to get everything on the CD.
Thank you so incredibly much - I sincerely appreciate your help!
I did just what you recommended and it worked perfectly!
For anyone else reading this with the same problem, here is how I did it:
- I copied the entire Photoshop CS4 to a USB Key
- plugged that in to my MacBook Pro
- made a New Folder on the Desktop of the MacBook
- copied all the items from the USB Key to the New Folder
- dropped the New Folder into the Macintosh HD on the MacBook
- then went to the Photoshop CS4 folder on the Macintosh HD
- double-clicked on the SETUP folder, and voila - it worked!
- Once I entered the serial number, the program downloaded and the only hitches were that it did not have the latest Adobe AIR version, so I had to go to the Adobe site and download a new version of that at www.adobe.com/go/getair
I am so thankful - Adobe would not work with me since I had the older version of CS4, so I was faced with buying a new version of Photoshop, not being able to use it on my laptop, and possibly buying Aperture instead - none of which I really wanted to do. So thanks again - you know your stuff and your help is greatly appreciated! Sincerely, Jimmy.
You're welcome. I'd like to also pass some credit on to whomever it was, some time ago, who reported back here on the forum that copying the installation files to the local hard drive worked where installing from external media did not, but alas I've long since forgotten the specific post.
