Hi ,
I think evaluation license is not having any working issues as already discussed previously.
The optisystem software is working quite appreciable and fine as per expectation even its 30 days trial versions.
I don’t think that the software has any problem, sometime it may have problem of”Could not obtain license, terminating application”
for this you should terminate the software using taskbar and restart the optisystem then it will work properly and smoothly.
hope this will help you in getting your problem resolved.
