DWS software not working with L515 camera, possible fingerprint error
I am having problem trying to run L515 camera with RealSense DWS software. The camera was initially registered using my co worker email address and he downloaded the DWS software in his laptop (trial version). After that I registered the same camera using my email address and downloaded the DWS software in my laptop (licensed version). I followed the user guide and generated the necessary license file, and did all the necessary steps. But unfortunately the camera doesn't work in my laptop.
I am able to run the DWS software in my co worker's laptop using the license file, but when I try to do same thing in my laptop it doesn't work. Is it something with fingerprint combination associated to different emailid?
Also when I try to run the sample code in visual studio in my laptop, the code builds and compiles without any errors but it gives fingerprint mismatch error in the console.
Can someone please help me out?

Hello Sizenn,
Confirming my understanding...
Your copy of the DWS Viewer Application is working correctly.
Your sample code is not working due to the fingerprint error.
Ensure you are using the same license for both programs. Copy the "License" file from the DWS Viewer folder into the folder where your sample executable is: C:\Users\sizenn.HLI\Documents_Projects\Intel_real_project\x64\Debug\
Let us know the result.
Sincerely,
Jesus G.

Hello Jesus,
Yes you are correct, my copy of DWS Viewer Application is working correctly but the sample code is not working due to the fingerprint error. And yes I am using the same license file for both programs, and the License file saved into the folder where my executable file is.
