Hello,
The EMS v1.6.x uses a License version 4. The new release 1.7.0, since it is a major release, requires the new v5 of our license. You can read the version of the license at the top of the license file itself.
The EMS will look for the license file in the following directories and in the following order:
/etc/evostreamms/License.lic
/usr/local/etc/evostreamms/License.lic
./config/License.lic
../config/License.lic
./License.lic
Please make sure you have the appropriate version of license in the right directory.
Bryan
