Hi, today I have some issues with some of our customer that complain about the appearance of the message “evaluation only”.
I don’t change anything, nor the version of the dll not even the license file.
Currently I have license file that has the tag 20180109 and file version of groupdocs.viewer is 17.12, that has been released on 12/21/2017 according to your site (https://downloads.groupdocs.com/viewer/net/new-releases/groupdocs.viewer-for-.net-17.12-(dlls-only)/ ).
I also check that the folder where are located license and dll are reachable and not read-only.
Can you help me?
