Quote - no good. it's mitsuba that won't run

seems your AMD (later chip than mine) has the needed instruction set. below yours (at least) is iffy.

 

Hmm...it should since... "The program currently runs on Linux, MacOS X and Microsoft Windows and makes use of SSE2 optimizations on x86 and x86_64 platforms." (Direct quote from the Mitsuba homepage.)* *

Just guessing, but you've got something else conflicting.

Now what that might be...not even a vague glimmer of an idea here.* *
