Lic error LERR1003 while uploading

I am having license file issue. when I am choosing the licence.dat file which I get from the application installation, it is showing error as invalid license file .
when I am, attaching the dat file which I received on my registered mail id it is showing error as “LERR 1003-Licence Validation Failed.”

No, it is my laptop. How can i resolve this issue? i have uninstalled the earlier and again did it but same error. While fresh installation studio will launch perfectly fine and i could create processes as well but next day it will ask to upload lic file and when i do it this LERR1003 error is thrown.

Hi,

Check mac address of your system by ‘getmac’ command in cmd. Also, while doing fresh installation did you used old set up or downloaded a new exe and then did installation
