The main question remains, had IH the full sum of money in order to meet the obligations of the license agreement at any time available?. The answer is no!
Speculation as to how they could have raised money is superfluous, because they have signed a contract with the knowledge that they can possibly not raise the sum and so they could not be interested seeing Rossi successfully running a long term test - because they did not have that $89 million at no time!
They had commitments from Woodford (looking at documents it is clear) to supply $200M+ should they be able to reproduce working reactors. Basically, had Rossi done IP transfer (and had working reactors), they were in a position to exploit this. That included paying off Rossi. See the Cassarino notes. It is pretty obvious they would be able to do this. IP transfer comes strictly before the GPT - so without IP transfer they are not obligated to pay) even if the GPT is real and OK).
The arguments from you and SSC here are particularly bankrupt, and notably they contradict each other. SSC and Ele seem to think IH was at fault for having too much money. You claim they are at fault for having too little.
When it is on record that they had access to lots more money but the conditions to get this never happened.
