My end-users get an error code when trying to execute the Activation Code (.ruac file) with the RUpdate tool. But this error is not specified in RU_Tool readme file!
Most probably this error code is related to the DataObject you want to update in the CRYPTO-BOX. Please refer to error code description for the DataObjects (DO) API in teosdo.h (see [PPK root]\SmarxOS\API\Win\SDK\MSVC\Include) for further details.
