Bob Holt plans to return out of administration after the end of the season, at the end of April.
Sir Seton Wills has offered Swindon another £1,000,000 but the club is having problems getting this money into the club in time.
Bob Holt said: "Clearly the club does not have enough funds to trade on its own.
"It needs the injection of funds from a third party. Those funds have been available for some time, but we have been unable to put them in."
