The three New York suits, which had been combined, questioned whether some of the online banking functions in certain versions of Intuit's flagship Quicken personal finance software were clear of Y2K problems.
Intuit has argued that no customers have been harmed because the software will work until the end of next year, and the company promises to have free fixes available by then.
The New York cases were dismissed December 1 by the Supreme Court of New York.
"Once again, a court has found that no consumers have been damaged and that none will be," said Allison Hubbard Colgin, senior corporate counsel at Intuit. She said the company is making sure all its Quicken online banking customers are Y2K-ready.
The California suit dismissed August 29, Alan Issokson vs. Intuit, has been combined with two other California cases, Colburn and Rubin, and is proceeding through the courts.
The Issokson suit was filed over whether online banking functions in Quicken 5 and Quicken 6 for Windows and versions 6 and 7 for Macintosh properly addressed Y2K issues. According to a Y2K section on Intuit's Web site, the company acknowledges problems with some versions of Quicken.
Intuit said it will make free patches available for download and by other means to all Quicken online banking customers by June 1999 to make its software Y2K-compliant. The Web page also describes the Y2K status of various Quicken versions.
