[csias40]

i KNOW THIS HAS BEEN ASKED, BUT READING THE OTHER POSTS, I STILL CAN'T DO IT.
i DOWNLOADED AND EXTRACTED, BUT WHEN I RIGHT CLICK AND EXECUTE, NOTHING HAPPENS.

i AM TRYING TO DOWNLOAD THIS PROGRAM.

DOWNLOADED AND EXTRACTED... TRIED MULTIPLE LOCATIONS.

I WISH IT WAS IN SYNAPTIC!

I REALLY DON'T KNOW TERMINAL, SO I NEED A TRUE STEP-BY-STEP.  EVEN SOME OF THOSE MAKE NO SENSE TO ME, OR DON'T WORK.

TRIED TO POST THE SCREENSHOTS, BUT IMAGE FILES ARE NOT SUPPORTED FOR THESE POSTS.

WHAT AM I MISSING?
