How do I set up Fiddler in Norton 360? Getting Error: 8921, 243 upon Live Update

Hello, I am trying to set up Fiddler as my local proxy in Norton 360.

 

I have done the following:

 

Brought up Norton 360.

>Go To Settings

>Administrative Settings

>Network Proxy Settings [Configure]

>Under the section "Proxy Settings" [checked] "Use a proxy server for your HTTP connections [Typed Address:] http://127.0.0.1 [Typed Port:] 8888 Click Apply Click Ok

 

When I tried to run Norton Live Update, I get the following error:

 

Norton 360

6.4.0.9

Error: 8921, 243

Windows 7 Home Premium

7601.17944.amd64fre.win7sp1_gdr.120830-0333

If you have sucessfully set this up, please let me know how you did it.

Thanks
