CS3 photoshop and acrobat 8 wont install

Would be grateful for any advice.

I have two macs an imac desktop about 12 months old running 10.4.11 with Panther and a newer one with Leopard running 10.5.5

Decided to install CS3 on the newer mac and it refused to install the photoshop and acrobat 8 programs. Has anyone else had this problem? Is there a fix.

The older mac runs everything OK. I have heard of this issue elsewhere.

Any suggestions welcome

I don't think it will prevent it from installing, but I do know that Acrobat 8.0 is not Leopard compatible. It opens, but it does goofy stuff with your documents. After installing it, you need to download and install the updates to bring it up to version 8.1.2 before it will run properly.
