It's a 32-bit binary and you only have 64-bit libs. You need to install the 32-bit version of GTK+ and I would guess a few others.

So i went to their website and downloaded the .bin file for linux. So i ran chmod a+x AdobeAirInstaller.bin to make it executable and then ran sudo ./AdobeAirInstaller.bin. I remember i did this and successfully installed adobe air on Ubuntu but now in arch it throws an error. Error loading the runtime (libgtk-x11-2.0.so.0: wrong ELF class: ELFCLASS64). I am using 64 bit arch. Please help. Thanks
