Dear User,
Thanks for raising the concern.
As you have mentioned, the installed runtime environment is of recent version.
Thus, the problem doesn't seems to be related with it.
Could you please check if your application is using integrated license manager that might be old ?
Please check if replacing the 'hasp_rt.exe' file with its latest version helps.
To get the latest hasp_rt, please run the master key introduction and collect the same from 'runtime API' folder such as below:
C:\Users\<Username>\Documents\Gemalto\Sentinel LDK 8.0\API\Runtime\DotNet
Looking forward to the results.
Thanks,
Parth
