I am trying to upload the Tax Table for GA, and I get the following error...

A critical error has occurred.Could not load file or assembly 'FileHelpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=3e0c08d59cc3d657' or one of its dependencies. The system cannot find the file specified.

Any help would be greatly appreciated.

The filehelpers.dll is included in the SmithCart install zip which can then be copied to your \bin folder. The reason its not copied during the install is because it requires full trust.

Thanks for the responce.

I RDP into the server and copied the file into the DNN\Bin folder.  When I do that I get the following results.  How do I load the filehelpers.dll file?

Hi Randy,

The reason the filehelpers.dll is not copied during the install is because it requires a full trust environment. Are you running the Cart in a full trust or shared environment?

Thanks,

We have installed DNN on our dedicated Server that we control.  It is a Windows 2008 Server, and we just did a standard install of DNN.  When I look at the “.NET Trust Level” in IIS it shows “Full (Internal)”  So I am not sure if that says we are running in Full Trust.  But I believe so.  Again, when I copy the filehelpers.dll file into the Bin directory.  The whole sites craps out, until I move the file back out.  I have looked at the Windows Security settings on the DLL, it is the same as any other file in that directory.  Is there something I am missing that I need to do?

Check your web config and make sure you have the following line for full trust:

 

<!-- set code access security trust level - this is generally set in the machine.config -->
<trust level="Full" />

I'm having the same issue:

1) initially received error "A critical error has occurred.Could not load file or assembly 'FileHelpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=3e0c08d59cc3d657' or one of its dependencies. The system cannot find the file specified."

2) after copying FileHelpers.dll to /bin folder it received following error:

 

Server Error in '/' Application.

Request timed out.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Web.HttpException: Request timed out.

Source Error: 



An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

[HttpException (0x80004005): Request timed out.]

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.237

Our DNN is hosted with PowerDNN.

What should we do next?

So do I need to reinstall Smith Cart after making that change?  Because if I copy FileHelpers.dll to the bin directory, I get the same blow up message as Dave.  Also, if I reinstall Smith Cart, what will happen to the information I have loaded into our shopping cart?

Hi Randy,
No need to reinstall SC, I recommend one of the following to options:

1. If you need to use the tax import you will need to configure your site for full trust, the reason your getting that error is because your site is not running full trust required by the filehelpers dll

2. Remove the filehelpers dll from your bin folder but you wont be able to use the built in sc tax import. As an alternate solution if you are unable to configure full trust you could use the ssms import wizard to import your tax data/
