Just for a point of inquiry, what it it that Dreamweaver needs Java Runtime Environment for?

And martiantime, it's not MAC, which means Media Access Control address, which is common to Macintosh computers as well as PCs, it's a Mac or Macintosh.

Apple quit supplying Java last October after security breaches of OS X caused problems.

If Dreamweaver does require Java, then you should take these steps to secure your Mac, except you may need to enable Java as long as it doesn't come from the Internet. You would certainly want to uncheck the box next to “Enable applet plug-in and Web Start applications”

I'm in the same boat with you. I recently used Time Machine to backup my profile and then wiped my entire drive and installed Mountain Lion. After importing all of my data with the Migration Assitant, Dreamweaver will NOT open.

SnakEyez02, Oracle's website does NOT have the dowload. The link you posted is to version 7. We've been down this road already. Martiantime is correct, neither Apple nor Oracle are providing Java SE 6, but Dreamweaver is crying to have it installed.

So, Adobe, how do we get out of the hole that we did not dig?

That page works for me.  Downloads a DMG file.  It's Java 7 and works fine.  I'm using it with DW CS6.  I don't think you can install multiple java runtimes.  If this isn't working, can you try running DW in another user profile on your Mac and confirm this is not a corrupted user account?

Found it!!!!!!

Download the file and install. It installs Java SE 6 update 11 (version 1.6.0_37).

Dreamweaver fires right up! Safari quits complaining as well.

I'm going to see if I'm successfull with updating to Java SE 7 now that I found six.

Should this test fail, I found this link to dig myself back out of it: http://support.apple.com/kb/HT5559?viewlocale=en_US.

UPDATE: Installed Java SE 7 udpate 9 and it worked. The Java Preferences App, under Utilities, shows that SE 6 is still installed. So, I'm thinking that this version is used to run locally on the system. 

I followed MHOLLIS55's suggestion and secured my Mac as well.

I've just switched from PC to iMac and got the Dreamweaver/Illustrator java runtime problem. As soon as I try to open Dreamweaver it asks for =java runtime which it then can;t download. Got brand new iMac with Mountain Lion updated today.

I've read this thread and visited the recomended page (http://www.java.com/en/download/manual.jsp) and downloaded & installed. I've got a java icon in my system preferences which tells me I've got Java Standard Edition v7 update 15). In the java tab of the control panel it tells me the runtime version is enabled.

BUT

1) Dreamweaver still won't start

2) I get same message from java preferences in Utilities

Suggestions please
