To open “MultiBit” you need to install the legacy Java SE 6 runtime I am unable to resolve this. I have updated Java but it appears to require a previous version. Thank you.
if you are using OS X, you can just double click

/Applications/MultiBit.app/Contents/Resources/Java/multibit-exe.jar

works on OS X 10.10.1, Java 7 Update 71.

guess they need some minor adjust for less strict JVM/JRE version check...
