License Server Reset
If problems with the License Server or activated licenses occur, you may have to reset the License Server. All details about activated licenses on the License Server are compiled in files that start with "taclic" and have the .data extension. The file name string after "taclic" can differ. An example of the License Server file name is taclic_00249e00_tsf.data. The license details files are created the first time a license is activated on the License Server. By deleting the files you reset the License Server.
The license files are located in \ProgramData\FLEXnet.
Before deleting the License Server files, you have to return all activated network licenses to the License Activation Server.
If you delete the License Server files, all activated network licenses are lost.
