I tried Coloc2 for the first time today in 2 different computers. On both I get this error after the window where I select images and algorithms:

`(Fiji Is Just) ImageJ 2.0.0-rc-43/1.51i; Java 1.6.0_24 [64-bit]; Windows 7 6.1; 62MB of 6059MB (1%)

(the other computer is running Imagej 1.51p)

You're still running on Java 1.6.0 (Java 6). Please make sure you're running on Java 8 and then enable the Java-8 update site. See http://imagej.net/2016-05-10_-_ImageJ_HOWTO_-_Java_8,_Java_6,_Java_3D#Upgrading_an_old_installation

thanks, this helped. I thought I had both my ImageJ and Java up to date, but was not aware of these additional manual steps.
