Can't run install.sh

I cannot run the install.sh file

this is what I get:
brandon@brandon-VPCCW21FX ~/Programs/Ardour3-3.1 $ sh ./install.sh
sh: 0: Can’t open ./install.sh

do this:

sh install.sh

or:

./install.sh

hi! I’ve already downloaded and I couldn’t find “install.sh”. Meanwhile a couple of file that seems an instalation file: “waf” and “wscript” are in my ardour instalation directory. Anyone can help me? Brgds and many thanks

@renzogiova: you’ve downloaded the source tarball, not a binary ready-to-run package.

@paul many thanks for your response. I downloaded the source code because I didn’t find a binary ready-to-run package after pay. Could you send me a link? Brgds

renzogiova: there are no links. The download system doesn’t work that way. If you paid via http://ardour.org/download and didn’t get a working link/redirect, email me your Invoice ID (via help@ardour.org) and I will fix things up for you.

I just sent an email with your request.
Tks and rgds
