Can't install Photoshop Extended on Mac 10.5.4 components failed

Question

One of our professors has a brand new iMac running 10.5.4
The machine has 4 GB of ram and Photoshop has never been installed on this system before.
The only Adobe product on the machine is Acrobat 8. (Not the reader - the actual program.) I tried to install Photoshop Extended - not from the Creative suite DVD set, but as a stand alone product that we bought.
The problem is the software will not install. I get the error message that the components failed.
I am in the administrator account.
The installer runs very slowly and then says that of the three components (one being Photoshop) only the shared components installed. The other two failed.
Any ideas?
Thank you,
John

Routine maintenance is imperative.
I still advocate Repairing Permissions (with Apple's Disk Utility) before AND after any system update or upgrade, as well as before AND after installing any software that requires an installer that asks for your password.
I have seen software installations go sour because the installer did not find everything as and where it should be.
I have also seen software installations go bad because the installer did not clean up after itself properly and did not leave everything as and where it should be.
This is just my own personal opinion and practice based on my own observations. Others may disagree and that's OK. I can only base my routines and my advice to others on my own experience and conclusion. I don't pretend to know why others believe otherwise.
Repairing Permissions after the fact (i. e. not immediately before and after an install) seldom helps.; Try it anyway, though.

Additionally, if your machine does not run 24/7 so that it runs the daily, weekly and monthly Cron Scripts in the middle of the night as intended by Apple, run Cocktail (shareware) as well.
Cron Scripts are maintenance routines designed by Apple to run on a daily, weekly and monthly basis in the middle of the night.
If you don't run them, you WILL run into trouble, sooner rather than later.
Here's an excerpt from the Apple tech doc
http://docs.info.apple.com/article.html?artnum=107388
Mac OS X performs background maintenance tasks at certain times if the computer is not in sleep mode. If your computer is shut down or in sleep at the designated times, the maintenance does not occur. In that case, you may want or need to run these manually.
Mac OS X periodically runs background tasks that, in part, remove system files that are no longer needed. This includes purging older information from log files or deleting certain temporary items. These tasks do not run if the computer is shut down or in sleep mode. If the tasks do not run, it is possible that certain log files (such as system.log) may become very large.
Also, from:
http://docs.info.apple.com/article.html?artnum=106978
The disk activity generated by find is a normal part of file system maintenance, used for tasks such as removing invisible temporary files that are used by the system. It is scheduled to occur early in the morning at 03:15 everyday, 04:30 on Saturdays, and 05:30 on the first day of each month.
NOTE:
There have been comments to the effect that Apple "fixed" this in 10.4.2 and later versions of the OS, but I have not been able to verify this to my satisfaction. The reference in the 10.4.2 release notes are far from explicit on this subject.

If you have DiskWarrior, run it regularly too.
