When your LabVIEW Application distributed with BLT is running without having connectivity to the Licensing Server (no Internet), BLT will take care of caching some information locally into the License file.

Once the connectivity with the Licensing Server is re-established, BLT will transfer this cached information back to the Licensing Server and cleanup the License file stored locally.


The information being cached contains:

•Error Logs (using the LogErrorMessage.vi)

•Product Feature Usage (using the IncrementFeatureUsageCount.vi)



If the LabVIEW Application is working Offline for a long period of time and have too many information being cached into the License file, this can lead to the License file getting too big and corrupted at some point (forcing the customer to reactivate the Product). To solve this issue, you can choose to Disable caching information into the License file.


How to disable caching Error Logs to the License file when working Offline?

•Set the file at "%ProgramData%\STUDIO BODs\<App Name>\enable_error_cache.ini" to 0 in order to disable caching errors to License file. Default is 1 (enabled)
(Create the file on disk if it doesn't exist already)



How to disable caching Product Features Usage to the License file when working Offline?

•Set the file at "%ProgramData%\STUDIO BODs\<App Name>\enable_featuretracking_cache.ini" to 0 in order to disable caching errors to License file. Default is 1 (enabled)
