Summary

This article discusses the "Failure to create a feature collection from trusted storage: [1,7e1,2,1[74100008,5,1202014d]]. Internal" error.

Question

Assume you have a device built with flexnet_client-xt-c-i86_windows-2017.02.1 that has a uncounted license in trusted storage. Then you make two builds of your software: Release and ReleaseWithDebugSymbols. The ReleaseWithDebugSymbols build works perfectly, while the Release build gives the aforementioned error. Why?

Answer

The error is saying that the C XT kit layer is attempting to call a function in FlxCore that does not exist. Given the context, the C XT kit is likely trying to populate the Final Expiration value of a feature. This functionality was added in FlexNet Embedded 2017.02.

The only way this could happen is if the FlxCore DLL being loaded is one from a previous release which does not contain this functionality. Take a look at the FlxCore which is being used by the particular build having the issue.
