A news report on the Balkan Insight website said the high court of cassation and justice jailed Gabriel Sandu for two years for money laundering, abuse of office and bribery.
The other three people involved were Gheorghe Stefan, the former mayor of the eastern town Piatra Neamt, and two businessmen. They were given jail terms of up to three years for acting as middlemen. The court's verdict can be appealed.
The four men were also fined about €10 million.
During the trial, the four men told the court they used their influence to get the government to approve the purchase of Microsoft licences. They then took kickbacks from others who had an interest in seeing the deal go through.
The deal was worth US$105 million and was meant to supply Microsoft Office licences to school. Prosecutors said the four men embezzled the 47 per cent discount that Microsoft offered the government.
The men also solicited bribes to ensure that Fujitsu Siemens Computing would get the contract, at a price that was bloated by 40 per cent.
Investigations showed that US$20 million of the total $US54 million paid by the government went in commissions to public officials.
The investigation noted that while Microsoft products were involved, the company itself was not implicated of any wrongdoing.
