I am 5of7/binary addend/unimatrix1517 and we cannot figure out how
to get linux to assimilate the realplayer.

These RealPlayer humans are dangerous.

I went to the site suggested and tried the code: chmod +x
RealPlayer11GOLD.bin and it returned with the error; "file or
directory does not exist".

I tried: "./RealPlayer11GOLD.bin", and it informed me that said
notation was a 'file or directory'.

So a file or directory that does not exist is seen as a file or
directory and therefore cannot be installed as a file or directory.

Evidently resistance is not futile.
