Q: Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

You are running what version of OS X? Your profile shows Leopard.

You can install this - Apple Java 2014-001 - which should be a working Java 6 that runs with Yosemite. However, I believe you may be using an older version of the Adobe software and should look into upgrading if that's the case.

Kappy, thank you so much for suggested link - IT WORKED for me :-)   I had not tried to open Illustrator after going to Yosemite and I was in a panic!  

Hi,

I had the same problem after upgrading to Yosemite. Illustrator CS6 wouldn't open. I got a message saying I should 'install legacy Java SE6 runtime'.

The link didn't work - it lead to a blank page.

So I downloaded Java8 (latest version) from Oracle but didn't install it. Something told me this was not the right way to go (the problem was with Java SE6, not 8). I then called Apple (in the Netherlands, were I live) for help. I got none. The best they could do was blaming Adobe for the problem or me, for not having the latest Adobe CC app. Rubbish.

And then, magic. I tried to open Illustrator again, got the pop up message but this time the link worked. It took me to an official Apple page, with a link to download Java for OS X 2014-001. The problem is now solved.

If curious, this is the explanation Apple gives for the problem:

'Java for OS X 2014-001 includes installation improvements, and supersedes all previous versions of Java for OS X. This package installs the same version of Java 6 included in Java for OS X 2013-005. On systems that have not already installed Java for OS X 2012-006 or later, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled 'missing plug-in' to download the latest version of the Java applet plug-in from Oracle.'
