Good idea using your chromebook with TripleA this way! I played around with that about two years ago, too.
How much RAM does your old computer have? Also is it Windows 7 32bit?
I assume you have the latest Java 8 already installed?
Also: The files of TripleA are present after installation - please check in c:\Program Files\TripleA (… unless you have not changed the install directory)?
Without knowing further details I assume that you have the same issues that we solved starting from here:
Please check and try and report back.
