Multiple applications crashing

Question

I'm on a 2002 TiBook with OSX 4.11 and last Sunday my apps started crashing. I first noticed the screen saver wouldn't come up, then discovered I can't open iPhoto, iTunes, Palm and who knows what else. They open, very briefly, then crash. The report reads, "EXEBADINSTRUCTION," near the top afterward. I am unable to copy and paste the report here.
Immediately preceding these problems I installed the Mac update, "Migration and DVD/CD Sharing Update," (v.1.1.) I have already dragged it to the trash and emptied that.
The Tech does not know why this is occurring and before I pay him even more to doodle around, was hoping to get some suggestions here.
I have a version of Tiger on a disc, and have already tried to use that (opened it, pressed the Restart button as indicated.) No significant changes.
Can anyone help me?
Thank you,
Kris Keller

Did you repair permissions before and after the install? You should also run Disk Utility's verify as instructed below.

I copied this from BDaqua:
Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
