Help Viewer local help proxy problem

[JohnH]

Since I added a proxy server in local network I can no longer use local help (Help Viewer 1.1), viewer content will only show an error page coming from my proxy. The local help urls are 127.0.0.1 ones. Computer internet settings are set to use a wpad.dat configuration file (that also exclude local addresses).

HlpViewer.exe.config (in folder C:\Program Files\Microsoft Help Viewer\v1.0) can be configured for proxy settings in <system.net> element, but all my attempts at defaultProxy/Proxy/bypasslist elements to avoid using the proxy have no effect. The only indication I've had that Help Viewer actually use this file is when I add something wrong Help Viewer crashes on startup. I also tried disabling proxy in HelpLibAgent.exe.config, HelpLibManager.exe.config and any other configuration file in same folder.

Anyone knows how to force Help Viewer to not use proxy?

I reconfigured computer LAN settings with manual proxy information (and exclusions), checking 'Bypass proxy server for local addresses' also affect Help Viewer allowing local help again.

Researched more and found a tip here c# - Using Proxy Automatic Configuration from IE Settings in .Net - Stack Overflow to use .pac extension for wpad script. Strangely, Help Viewer will work with this setting (but not with .dat extension). I also checked with .Net requests and the detected proxy information there, and that works correctly regardless of wpad file extension.
