Unable to load library. Error code: 0x0000007E::Pkcs11Interop on Win2008

[vizd...@gmail.com]

Hello everyone,

I am currently trying to host a .Net MVC app on a win2008 server with .Net 4.6.1. I have set everything correctly but it keeps throwing this error:

Unable to load library. Error code: 0x0000007E::Pkcs11Interop
at Net.Pkcs11Interop.Common.UnmanagedLibrary.Load(String fileName) at Net.Pkcs11Interop.LowLevelAPI41.Pkcs11..ctor(String libraryPath) at Net.Pkcs11Interop.HighLevelAPI41.Pkcs11..ctor(String libraryPath, AppType appType) at Net.Pkcs11Interop.HighLevelAPI.Pkcs11..ctor(String libraryPath, AppType appType)....

When I print the path variables it points correctly to the right locations. I have provided the permissions as well to the IIS User.

Not sure what I missed.

Any help will be greatly appreciated.

Thank you
Vishal Singh

And I am correctly trying to load 64 bit for both Pkcs11Interop and PkcsLogger since it is 64 bit system.

If this is .net, make sure that in project properties, under the build tab, the platform target is x64

It is configured for Any CPU, however I tried with specific with x64 as well but still the same issue. Checked all the permissions, environment variables are correctly set too.
On my local desktop it works fine. Only when trying to host it on a server.

Thank you
