Is it possible to install OpenCobalt into Squeak 5.2

Open Cobalt
"http://opencobalt.org (Best to run this from an image in an open
cobalt directory)"

Installer ss project: 'TweakCore'; install: 'update'.

[Installer ss project: 'TweakExtras'; install: 'update']
	on: (Smalltalk at: #CUnsynchronizedModification) do: [:ex | ex resume].

Installer cobalt project: 'Tweak';
	answer: 'Would you like to conserve memory at all costs?' with: true;
	answer: 'Password for interactive VNC connections?' with: 'cobalt';
	answer: 'Would you like to add the RFBServer to the World open menu?'
with: true;
	install: 'update'


I wonder what an open cobalt directory is.
