TOPEKA — A state computer system that was supposed to launch more than five years ago has been delayed again, the Kansas Department of Revenue announced Wednesday.

KanLicense, a KDOR project, would replace 30-year-old mainframe computer systems used by examiners to issue Kansas driver’s licenses and identification cards. It was slated to come online Jan. 2, six years after its initial targeted launch date.

According to a news release from KDOR, the project was delayed to ensure a “successful rollout.” Earlier this month the project looked like it would be ready to go live Jan. 2. When auditors placed the project on “caution” status a week later, she would not say whether officials still believed the project would come online as scheduled.

The release did not say how long the delay would be. County and state officials would have been required to work on New Year’s Day in order to roll the project out on Jan. 2, which would no longer be necessary.

KanLicense has been rife with difficulties and delays. It has been nearly six years since KanLicense was planned to launch, and the state had to sever a contract with 3M, the company it originally picked to build the program. The state rolled out a new system in May 2012 for issuing vehicle titles and registrations, but it resulted in delays and complaints for users.
