Hello dear SciChart team,

Our customer has a new security program that starts on Dlls that are copied into a directory during runtime. At the moment has the customer the problem that this security program starts on an AbtLicensingNative.dll. This DLL is in the following directory:
% USERPROFILE% \ AppData \ Local \ SciChart \ Dependencies \ v.6.2.1.13304 \ x64.

For this reason the following questions:
Is this DLL safe?
Why is the dll only copied at runtime? Is there another solution for this?

best regards
Silvester

Version
v.6.2.1.13304

Hi Silvester

Writing the files at runtime is the only way that this can be done right now, however you can specify where to write the files too and add an exception to anti virus software.

Try this code before any SciChart library code is called:

SciChart.Core.NativeDllLoader.DependenciesPath = "C:/Temp"; // Or a directory of your choice

Now instruct the user to set an exception in their antivirus for c:/temp

Please let me know if that helps,

Best regards,
Andrew

    Thanks Andrew for quickly info. I forwarded your response to the customer. They answered me that their main concern is that such dlls are digitally signed. Then the DLLs are accepted by the safety program. I’ve looked at the DLL on my computer and it actually doesn’t have a digital signature. Is it possible or is it planned to sign the licensing dll at some point? Best regards Silvester

    Hi Silvester, I can look into that for you. Are you able to try the suggested solution? It may take us some time to investigate and deploy a signed version of the C++ dlls.
