While on the homepage I selected to download 32 bit version of Aptana Studio. I have been then redirected to the download page listing a Linux download. I clicked on Download without changing any of the options and successfully downloaded Aptana_Studio_3_Setup_Linux_x86_3.3.0.zip
After extraction, I attempted to run the app and got "cannot execute binary file". After running 'file' on the executable I got this:
'AptanaStudio3: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.4.0, not stripped' which means it's a x64 binary which will not work on 32 bit OS.
