Data Export Extension Fails on Import

Hello!

That seems to be a known issue due to a JAR conflict since at least ThingWorx 7.4.

There was a thread already in the community for that, please have a look:

https://community.ptc.com/t5/ThingWorx-Developers/Data-Export-Extension-not-importing-won-t-validate/m-p/519974#62875%3F&posno=3&q=DataExporterExtension&source=search

As mentioned in the Marketplace and also in the thread above, the extension is not supported and it is delivered  in "as-is" condition.

I hope that helps!
