Pointwise Installation Problem

view full story

https://bbs.archlinux.org – I am trying to install the Pointwise grid generation software on Arch Linux and I am having a lot of problems. The installer has worked on every other computer I have (Ubuntu, RHEL, Debian, etc) but not on Arch.I don't know a lot about the way the installation works, but the install file is freely available at http://www.pointwise.com/support/dload_pw.shtml. My university gives me a license file so I can run it once it is installed, but I can't even get that far. Whenever I try the install I get the following error message:Preparing to install...Extracting the JRE from the installer (HowTos)
