Hello Matt, I'm not familiar with other users running IDL on 64-bit Intel Atom E38xxx series processors with X86_64 architecture. However, if the Linux version installed on it meets the minimum Linux kernel and glibc version requirements for the IDL version being used (for IDL 8.4): http://www.exelisvis.com/docs/Platfor... --as well as having all of the needed system library dependencies, I'm guessing you might be able to get IDL to run on such a system. In case it can be helpful, here's a link to a help article that discusses some common system library dependency issues for IDL on various flavors of Linux: http://www.exelisvis.com/Support/Help... Ultimately, if you have trouble getting the IDL Workbench (idlde) to work and you really only need access to IDL Runtime (RT) session to execute your compiled IDL application save (*.sav) files, you might wish to focus on getting IDL command line (idl) or IDL RT session (idl -rt) to work. Note that if you attempt to run idl -rt without proper licensing, then by default the session will launch in IDL VM (virtual machine mode) in which the interactively dismissed IDL VM splash screen will appear. You can also explicitly launch an IDL application in IDL VM mode use the idl -vm command line switch. Examples: idl -rt=/path/to/myapp.sav idl -vm=/path/to/myapp.sav Finally, here are some IDL help pages that might be of interest to you regarding IDL RT and IDL VM limitations: http://www.exelisvis.com/docs/Limitat... http://www.exelisvis.com/docs/Limitat... I hope this can help. Kind regards,
