Selecting the JDK version the IDE will run under

If your using PyCharm, and you get the message that you need to run JAVA SE 6, and you have a later version, say JAVA 7 or 8, the above link has information regarding a workaround.

The following information is from the above link. If your using a MAC (like I am), these are the instructions you'll need to perform:

At the moment all our products require Apple JDK 1.6 to be installed in order to run on Mac. JDK 1.7 from Oracle is not officially supported yet and has known problems that stop us from using it by default. Oracle JDK 1.7.0_40 has added support for Retina and works much better than previous versions on Mac. You are welcome to give it a try in case you have any problems with Apple JDK.

To force running under JDK 1.7 edit /Applications/<Product>.app/Contents/Info.plist file, change JVMVersion from 1.6* to 1.7* :

<key>JVMVersion</key>

<string>1.7*</string>
