Thanks for getting back to me, you were offline when I responded earlier.
Are you installing EasyShare from a disc?
What version is it?
Try downloading version 6.1 from the following website - click on the grey Download button.
Let me know if it installs ok for you?
Kindly rate my service positively.
You can reply back at any time if you need further instruction.
Please try the v6.1 download mentioned previously when convenient for you to do so.
Are you using Safari?
Do you have any popup blockers installed in Safari?
Have you checked your Downloads folder?
Easyshare is very old software and is no longer updated or supported so may not run well on newer versions of OS X.
However the pictures that you stored with EasyShare should still be on your old computer somewhere - installing Easyshare will not help you find them if you cannot access the photos on your old computer.
