Error when trying to view examples in LabView help

[Jens1968]

When pushing button to "open example" or "browse related examples" from within LabView help I get the following error

-----

ERROR

The requested URL could not be retrieved

---

While trying to retrieve the URL: http://127.1.0.1:3580/National%20Instruments/LabVIEW/LabVIEW/7.1/OpenVIFromHelp?

The following error was encountered:

• Connection Failed

The system returned:

    (111) Connection refused

-----

My IT-department are unable to help me. 

They state that this is a Labview related problem and not at problem originating from our firewall or similar.

In this forum I've found one guy having a similar problem 

(http://forums.ni.com/rss/message?board.id=170&message.id=192671 - only the address was ..127.0.0.1.. and not 127.1.0.1),

but unfortunately he never got an usable answer on his question. At least not anything that works for me.

Hope that I'm more lucky now!

In advance: Thank you very much for any help

Are you trying to do this while LabVIEW is not running? 'Cause that will happen if it's not running. Try it with LabVIEW already running.

LabVIEW is running! Then - from Labview "help" button - I open help and try to open e.g. an example.

Then the error occurs.

An college to me is having the same same, but he gets the 127.0.0.1 address, but else the same error message.

Strange....

Hope anybody can help us caurse I would be great to be able to se the examples (I'm very new to LabVIEW and need all the help I can get!)

As LabVIEW evolved NI seemed to think that it was a great idea to dump a whole bunch of services running on the computer jsut to get LabVIEW running with all the doo-dads. I suspect one of these is causing the problem. Regardless, that is not the only way to see the examples. The examples are on disk and you can easily get to them by going to LabVIEW's install directory and looking in the "examples" folder. You can also try the NI Example Finder rather than the Help. That's available from the LabVIEW menu bar, although I know that requires another one of those "essential" services.

I just fought this battle myself, and thought I would along what I found was helpful.

My example finder in LabVIEW 7.1.1  functionality was broken and I found that National was attempting to connect with Example Finder on my local machine using IP address 127.1.0.1, instead of the more common 127.0.0.1 address for localhost. The result was that the Example Finder HTTP:// request was being sent away from my machine using the Microsoft Windows Internet Explorer HTTP Proxy information to my corporate web proxy server. That proxy server was properly refusing to proxy the connection since 127.1.0.1 is a non-routable address.

The error message back from the corporate HTTP proxy server was the helpful item. Once I saw what was happening, I went into the Microsoft Windows control panel for internet options and on the connections tab, LAN setting button, ADVANCED button, entered 127.*.*.* into the field for "DO NOT PROXY THESE ADDRESSES"

Now the Example Finder requests are directed to the NI server on my local machine and the example finder is back to working.

This is the second time I worked this out, but I forgot what was learned the first time.... Guess we are all condemned to repeat our mistakes.
