Re: Library error on Windows 8 , Windows 8.1.

NCryptoki works on any Windows OS from Windows XP to Windows 8.1.

We have thousands of customers that are using NCryptoki and noone has got such a problem.

What PKCS#11 module (dll) are you loading?

NCryptoki loads a PKCS#11 dll to work. The problem may be due to such PKCS#11.

Re: Library error on Windows 8 , Windows 8.1.

You called OpenSession(1), this means that you are tryng to connect to the Slot 1. Are you sure you have two slots available (0 and 1).

Did you try to call OpenSession(0)?

Re: Library error on Windows 8 , Windows 8.1.

I can run this code in .NET FW 3.5 on Windows 8 , but I can't run this code in .NET FW 4.0 on Windows 8.

And

I can run this code in .NET FW 4.0 on other Windows (7,server2008 R2).

Re: Library error on Windows 8 , Windows 8.1.

I guess the problem is related to cryptoki.dll that you are using on that Windows 8.1 installation.

Are you working on 32 or 64bit system?

On a 64bit system your .net application runs as 64bit and can load only a 64bit dll. check this.

Re: Library error on Windows 8 , Windows 8.1.

NCryptoki is a .NET assembly and it can work on both 32 and 64bit OS.

I mean cryptoki.dll, the dll of your PKCS#11 module.

Are you sure you are using the 64bit one?

Re: Library error on Windows 8 , Windows 8.1.

Hello

cryptoki.dll we are using is from x64 driver, so it should be 64-bit. Basically, if we run the project using .NET Framework 3.5, it works without such error. However, when we attempt to use .NET Framework 4.0 or higher, we received the following error:

An unhandled exception of type 'System.AccessViolationException' occurred in NCryptoki.dll

Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Re: Library error on Windows 8 , Windows 8.1.

It's very strange. We never seen this error till now.

Can you send us the stack trace of the exception?
