I found another thread that restores Internet Sharing

Edit the registry as follows:

Open "HKEY_LOCAL_MACHINE\Comm\InternetSharing"
Delete string named "Extension" (value = rilphone2.dll)
Check string under Settings "MaxCMConnectRetries"
If value = 1, then change it to 0,
If value = 0, leave as is
Close registry

Soft reset and Internet Sharing will now connect without Error Code 67
