From: Schaber on 1 Dec 2008 07:00 Hi, Each time I start Mathematica 6 and sometimes when displaying graphics, I get the error message "JLink`InstallJava::fail: A link to the Java runtime could not be established." But I have Java 6 update 10 installed. Any idea? Thanks, joerg

I do remember someone else reporting something similar, and it turned out to be a clash with other software on their machine. Try temporarily disabling your virus scanner and see if the problem goes away. David Bailey http://www.dbaileyconsultancy.co.uk

That would be me. It was pervasive on campus and on home computers. The problem went away when we added an exclusion for the Mathematica installation directory in NOD32. I think the issue went away with a later release, though (6.0.2ish) and we no longer need the exclusions. -- Helen Read University of Vermont
