Cannot install from a .run file

view story

http://forums.fedoraforum.org – Hello everyone, I am trying to install a Java utility from a .run file, without any success (JXplorer LDAP browser as it happens, though I don't think that is relevant).File is executable Running as root No error message or output of any kind - just goes straight back to command line prompt No activity visible with top or ps -ef SELinux is "Permissive" Running on F17 x86_64 (kernel 3.8.13-100) I can install the same utility from the same .run file without any problem on another F17 x86_64 machine where it runs perfectly. Any ideas what is going wrong? Thanks, Andrew (HowTos)
