Cannot Import 'ptc-windchill-extension-1.6.0-01' extension into Thingworx 7.1.19
Hello,
To start with, I am beginner in Thingworx. I just had my thingworx 7.1.19 installed with postgres as database. I brought up the UI and can able to navigate around and do basic entity creation like thing, thingtemplate etc...
Now trying to import the PTC Windchill extension (ptc-windchill-extension-1.6) into thingworx, but it fails and all I can see in log is below error message, not sufficient to troubleshoot, not sure what I am missing.
1. Is there any compatibility issue.
2. Am I missing any steps before importing the PTC windchill extension.
