# Players Not Downloading Presentations with Special Characters

It is possible to upload presentations that contain certain special characters (e.g., "+"), but the Storage server will return a 404 error to devices that attempt to download the presentation. Use one of the following workarounds to fix this issue:

***

Add the following parameter to the root Web.config file of the BSNEE Storage site, which is hosted on IIS:

```text
<system.webServer>
     <security>
          <requestFiltering allowDoubleEscaping="true"/>
     </security>
</system.webServer>
```

***

Use the IIS Manager UI.

1. Select the storage site.
2. Double-click **Request Filtering** in the **IIS** group.
3. Click the **Edit Feature Settings…** link on the right pane.
4. Check **Allow double escaping** and click **OK**.

***

Enter and run the following in the command line: `%windir%\system32\inetsrv\appcmd set config "BSNEEStorage" -section:system.webServer/security/requestfiltering -allowDoubleEscaping:true`

:::hint{type="danger"}
Make sure to replace "BSNEEStorage" with the name of your Storage site.
