Evaluating ThingWorx 8.5.0; Getting "License has not been installed" on the composer.

Hi,

We are evaluating ThingWorx 8.5.0 that is installed on a linux server. We are running the platform in a disconnected mode (no internet available). We are following the guide : https://developer.thingworx.com/en/resources/learning-paths/getting-started-on-thingworx-platform/thingworx-foundation-quickstart . We can create and save tags, ThingShapes and ThingTemplates. But on the step 5, while saving the Thing, we are getting "Licence has not bee installed" error. The same can be seen while importing the sample entities from other guide, creating Data Shape, Value Streams, creating a new user etc. Can you please help us understand what might be the problem?

We have generated ../ThingworxPlatform/licenceRequestFile.txt file containing device id.

We went through the Licensing Guide for disconnected sites (http://support.ptc.com/lm/ThingWorx_Navigate_8.1_Licensing_Instructions.pdf) . But getting 'Access denied:insufficient privileges' error due to trail version account. 

Please find the environment details as follows-

* ThingWorx version - Trial 8.5.0

* Tomcat version - 9.0.22

* Stack trace from catalina.out -
