Question

I’ve definitely got JDK 1.6.0 installed in C:\Program Files\Java\jdk1.6.0_35, but it never seems to be able to find it when I try to open the SDK Manager. In task manager, find_java.exe shows up until I stop it (will run for hours).

Are there some environment variables I have to set for this to work?
