FIFA's ethics investigator has closed the bribery case against Mohamed Bin Hammam.
The decision means Bin Hammam, who tried to challenge Sepp Blatter for the FIFA presidency, will not face new charges that he bribed Caribbean officials during his presidential campaign.
The Qatari had always denied any wrongdoing and earlier this year had a lifetime FIFA ban overturned by the Court of Arbitration for Sport because of a lack of evidence.
The court overturned a ruling by FIFA's ethics committee that the 63-year-old was guilty of paying bribes at a Caribbean Football Union meeting in 2011, but said his behaviour was "not of the highest ethical standard".
It also found that "it is more likely than not" that Bin Hammam was the source of cash brought into Trinidad and Tobago and distributed by former FIFA vice-president Jack Warner.
Michael J Garcia, FIFA's chief ethics investigator, has closed the case against Bin Hammam, and said in a confidential report to FIFA: "This investigation focused on events that took place at the CFU meeting in Trinidad and Tobago in May 2011.
"With respect to the events at the CFU conference, the investigation uncovered no new material proof beyond the substantial evidence presented during the proceedings that culminated with the CAS decision vacating Mr Bin Hammam's ban.
"Accordingly, the Investigatory Chamber has closed this matter."
Bin Hammam remains provisionally suspended over allegations of financial mismanagement while president of the Asian Football Confederation. That suspension is also being challenged in the courts.
