Hello Lin, I too have had problems myself in getting Photoshop installed - particularly with Dell machines. For a long time I was unable to get CS3 up and running successfully despite numerous attempts - installing, re-installing etc etc. It would seemingly install correctly and then crash when attempting to run it. After a very long period of 'research' (during which Adobe proved less than helpful), I found a solution on a forum somewhere. It seems that a batch of Dell machines were set up with the Welsh language as a keyboard default - this caused the crash on loading up. I would never have thought of that possibility in a million years! However, saying that, Adobe Bridge still crashes quite often despite numerous updates. These days I use an Apple Mac for my photo editing with either CS3/CS4 with no problems at all. The PC must remain (Windows XP) of course for PTE. The Dell machine will be upgraded eventually when the dust has settled regarding Windows 7. I abhor Vista and would not touch it with a baregepole... :-) My other issue with Adobe is the way they drop RAW support for older cameras with each new versions of Photoshop - even though the cameras affected are relatively recent or still in production. Thus forcing users to upgrade whether they wish to or not. And I know you can workaround this by using the DNG converter - but it's still a pain in the butt and shows Adobe's total disregard for the loyal users of earlier versions of this very expensive software...
