Adding X-Frame-Option "SAME-ORIGIN" Http Response Header in IIS

Behavior:
After enabling X-Frame-Options "SAME-ORIGIN" in your IIS HTTP Response Headers, the DocuWare Web Client results in a "500 Internal Server Error."

Solution:
Please implement the following steps to resolve this error message;

1. On the server the DocuWare installation is on, navigate to C:\Program Files\DocuWare\Web\Platform and locate the Web.config file.
   Note: Make a copy of the Web.config file as a backup!
    
2. Within the Web.config file, delete the following lines below:
   
     <location path="WebClient">
       <system.webServer>
         <httpProtocol>
           <customHeaders>
             <add name="X-Frame-Options" value="" />
           </customHeaders>
         </httpProtocol>
       </system.webServer>
     </location>
   
3. Save your file.
4. Create your HTTP Response Header by doing the following:
   Open IIS Manager, and on the left-hand tree, navigate to Sites > Default Web Site > DocuWare then double-click the “HTTP Response Headers” icon.
   
   Right-click the header list and select Add. Then for the name, write X-FRAME-OPTIONS, and for the value, write SAME-ORIGIN.
   

When all the changes have been saved, perform an IISRESET, and the Web Client should load without error.
