I cannot get Photoshop CS3 (French version) to open - I am told that "my copy is no longer valid or/ uninstall reinstall re-enter licence number". I tried this but it makes no difference.
Through the chat I spoke to Ahmed - he told me that Photoshop CS3 is definitely incompatible with Mountain Lion (?) and that I should reinstall Snow Leopard. I did this and it works - licence number is valid etc.
This does not square with the info on the photoshop blogs.
What I wonder is this - I was using CS3 happily on lion but I had a bad crash, I think due to a damaged cable and had to reinstall my system. I checked with Photoshop blogs etc - "no known issues with CS3". So I went ahead and bought Mountain LIon. at first no problem but then next day CS3 wouldn't open.
Could this really be a licence issue rather than a compatibility issue?

I just upgraded to ML and cannot open CS3 either. However, I get a warning that says I need to install Java ES 6, but when I click on install it says it is not available. I talked with Adobe support but was told they no longer support CS3. I then spoke with AppleCare and they didn't think CS3 is compatible with Mountain Lion. Looks like I'll have to spend another $299.00 to upgrade Photoshop. Frustrating! Did you ever find a fix?

CS3 is compatibile. Are you still having trouble installing Java? It sounds like a connection problem hiccup with Apple's update servers for downloading java from them - so I'd retry downloading today to see if it's still a problem. (We were able to download and install just now)

I don't know how to install the Java ES 6 it says I need. I went to the Oracle site but it was so confusing that I just left.

It's available from Apple. Did you click the link to download it from Apple?

Ken,

CS3 should run just fine on Mountain Lion 10.8.x.

One thing that we've seen happen during upgrades is OS X permissions get damaged. Have you tried running from a new admin user and/or Safe Boot?

I ran a disc permissions using Disk Utility and a very long list came up, which I had it repair. Still can't launch CS3 without getting the "need to install Java ES 3" warning.

I'm also wondering if you guys were running Photoshop in Rosetta previously: http://helpx.adobe.com/photoshop/kb/e...

I have since downloaded a trial version of CS6 and it works just fine.
