All the questions I've seen refer to running a 32-bit app in a 64-bit system.
I'm running 32-bit Ubuntu 12.04 (actually elementary OS Luna, which is based on it) and I'm trying to run a 64-bit app which refuses open. Running:
64bit_app.run is the 64-bit app I'm trying to run) results in:
bash: ./64bit_app.run: no se puede ejecutar el fichero binario
which translates to "can't execute/run/open binary file".
Should I be able to run it? Is it possible to run a 64-bit app in a 32-bit system? If so, how?
