Running Siebel Tools 8.x And IE 11 And Win7 x64!


I use Win 7 x64 as my development platform, i Develop on Siebel, I use IE 11. I’m heading for trouble thats for sure! ??

Allthough not perfect / not fully tested yet: this is a nice teaser:

It’s not all simple sailing. One of the big hidden things is that Siebel Tools do not like you start the dedicated client with a /b pointing to the x32 IE 11. I don’t know why… Annoying! It just fails!

Then when you set nothing:

Siebel Web Session
Cannot determine default web browser for current user.
Please set up your web browser properly or use the /B command line argument to specify one.
This annoying thing is what greets you the first many times, until you try the /b – which then does not work.

you then think ah! and surf and surf the web for somebody who’s been in your position – but there’s not much to be found.

Here are the simple step needed to fix the issue:

Open Regedit:

Navigate to


if there is no http key (folder) create it

in the http key create a UserChoice key (folder)

in the UserChoice key create a String Progid with a value of IE.HTTP

Like This:

Now the F5 Run will work!!! Yeah!

Note to self and others: the IE.HTTP actually points to the registry entry: HKEY_CLASSES_ROOT\IE.HTTP

Which in turn points to the x64 version of IE, but a x32 IE is started by Tools…. Go Figure…

    1. Hi Jon,

      F5 – debug works. I've had instances where it did not trigger, mainly if there are specific comment formatting in the beginning of the declarations section of the application script object. There is a SR# opened for this issue, It does describe the issues with the debugger.
