ePO 4.6 has a few other issues with license keys..
One of the MAJOR sellings points of ePO 4.6 was the software manager...but it only works if all your grant numbers are under one license key..
But, if you manage products under 1 epo server, but the products are acquired by different groups with different budgets, then you have separate grants and seperate license numbers...and suddenly that great software manager becomes pretty useless..
There SHOULD be the ability to enter MULTIPLE license keys....but no...
Only ONE license key...the one that holds the license for ePO, is supported..
