# Problem Loading the Ninject Assembly
## Symptoms

When installing the Coveo for Sitecore package or accessing your Sitecore instance, you might get the following error:

`System.IO.FileLoadException: Could not load file or assembly 'Ninject' or one of its dependencies.
The located assembly's manifest definition doesn't match the assembly reference.
(Exception from HRESULT: 0x80131040)`

## Cause

This issue arises when you already have the Ninject library on your website.
Upon installing the Coveo for Sitecore package, you will be prompted to overwrite your existing `Ninject.dll` file.
If you choose to overwrite it, Ninject version 3.0.1.10 will be deployed instead of your current Ninject library, therefore resulting in incorrect version numbers in your C# project references.

## Resolution

To fix this issue, follow these steps:

. Replace the `Ninject.dll` assembly in your website `bin` directory with the one referenced by your project.
. Using a text editor, open the `web.config` file and insert the following lines in the `assemblyBinding` XML element:

```xml
 <dependentAssembly>
   <assemblyIdentity name="Ninject" publicKeyToken="c7192dc5380945e7" culture="neutral" />
   <bindingRedirect oldVersion="0.0.0.0-3.2.2.0" newVersion="<YOUR_NINJECT_VERSION>" />
 </dependentAssembly>
```

. Re-install the Coveo for Sitecore package, but when prompted to overwrite the `Ninject.dll` file, choose **No**.
For all the other assemblies, you should choose **Yes**.

. Restart the Sitecore client and server when prompted.
