Error: Running EFDCPlus without license

Hi, I recently installed EFDC Explorer (EEMS8.4_Setup November 28, 2018) and I used the executable (EFDC_Explorer8.4.5 Executable - December 5, 2018).I desactivated the license and I’m trying to reactivate it in the laptop, open a saved project and try to run the EFDC and it shows the next error: “Running EFDCPlus without license” and everytime I closed the EFDC and I want to initiate EFDC I have to retype the license code.Can you tell me what is causing the error and how to fix it?Regards

This could be related to you using Spanish language settings for decimal place. EE requires a period rather than comma for these settings.
