Unable to Load the DLL: 'TBarCode11_x64.dll'

Unable to Load the DLL: 'TBarCode11_x64.dll'

You may receive this kind of error when you call an ASP.NET web page, which contains a TBarCode .NET Web Control or a Barcode Class from the TBarCode .NET Assembly.

The possible reason for this problem is that either the DLLs have not been installed or are not available for the IIS process. It can also be that the 32 Bit version has been installed but the IIS application pool is set to 64 Bit.

The solution would be to install our TBarCode x64 MSI setup and initiate a restart of the IIS service in order to make the IIS process read in the updated PATH variable.

Start an admin console (run as Administrator) and enter

iisreset

This will restart all IIS processes and afterwards the DLL should be found. The MSI setup installs the .NET component into the GAC and puts all dependencies (folders) into the PATH environment variable.
