Found that Adobe Photoshop CS5 won't run in Mac OS X Yosemite? Is it demanding that you 'install the legacy Java SE 6 runtime'? Here's how to fix the problem and get Photoshop CS5 to work in OS X. Mac OS X Yosemite (and the newer versions) are having a later version of Java Runtime (SE 8.0). However, Java Runtime is not backward compatible. So, even when the operating system have installed Java Runtime 8, it will NOT run apps that rely on Java Runtime 6.
This article explains how to install Java 6 32bit on Mac OSX 10.10 Yosemite.
Java 6 32bit is required when using the 32bit installer for PDF Studio – a powerful, low cost Adobe® Acrobat® alternative for Mac OSX. Note that the 32bit installer is no longer the recommended installer. The new recommended installer for PDF Studio is 64bit and does no longer require Java 6.
Steps to install Java 6 If you wish to continue with the old / original installer
Q: I upgraded my mac to OSX 10.10 Yosemite & 10.11 El Capitan and I am having trouble opening PDF Studio. I receive the message: “To open “PDF Studio 9” you need to install the legacy Java SE 6 runtime.” How can I fix this?
A: Like other applications such as Dreamweaver or Creative Suite, PDF Studio requires Java 6 in order to run. During the upgrade process to Mac OS X 10.10 Yosemite or 10.11 El Capitan, Java may be uninstalled from your system. In order to reinstall and run PDF Studio you will need to install the Java 6 Runtime again. You may receive a dialog that will direct you to the site where you can download the Java 6 Runtime. Once installed you can proceed as normal with installing and using PDF Studio. You can follow the instructions below to complete the Java 6 installation.
Installing Java SE 6 Runtime
- Click on the “More Info…” button. The “More Info” button may be broken on some Yosemite minor versions. If so, go to the Mac Support site (support.apple.com/kb/DL1572) to download Java 6.
- Click on the Download button on the Mac support page
- This will begin downloading the Java installer. You can see the current status of the download on your dock.
- Once the download is complete, click on the downloads icon on the dock to open the download folder. Then click on the file labeled JavaForOSX2014-001.dmg to open the download.
- Then double click on the JavaForOSX.pkg file to open the Java 6 installer
- Follow the installation instructions to complete installing Java 6 on your system
- Once the installation is complete you can proceed as normal with installing and/or using PDF Studio. In some cases, you may need to reinstall PDF Studio as well due to the way that the Mac OSX 10.10 upgrade rearanges the files on the system.

Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. It is now an optional install that you must select.
Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.
