Detecting the browser installed

I need some help detecting whether Netscape and Internet Explorer has been installed on the system.

I also need to retrieve the paths of these two browsers if they are installed

Thanks in advance,
WizKid

Here is a code for getting installation directory of Netscape:

uses registry;
...
procedure .....
var FDir: String;
begin
  with TRegistry.Create do
  begin
    OpenKey('Software\Netscape\Netscape Navigator\Main', True);
    FDir := ReadString('Install Directory');
    CloseKey;
    Free;
  end;
end;

How about Internet Explorer??
And does this work for all versions?

Is it possible to get the version number as well?

1. IE
In order to get details on Netscape you need to do some research on the registry file, that's how I got the installation directory. Since I don't have the IE installed in my computer, therefore can't make the inquiry. But you can, after you have seen the example.

2. Netscape versions.
I don't think that Netscape programmers (and any other good programmer, in general) will change the registry keys/values
names from one version to another, since it would be very difficult to maintain the sources.

3. Getting version number.
There are 2 ways to get it:
A. By getting the version of the Netscape Exe file, that is by calling GETFILEVERSIONINFO. An example can be found in:
http://www.borland.co.uk/devsupport/delphi/ti_list/TI3241.html 
B. By reading the registry file as follows:

procedure TForm1.Button1Click(Sender: TObject);
var FVersion: String;
begin
  with TRegistry.Create do
  begin
    RootKey:=HKEY_LOCAL_MACHINE;
    OpenKey('SOFTWARE\Netscape\Conference', True);
    FVersion := ReadString('CurrentVersion');
    CloseKey;
    Free;
  end;
end;

Thanks for guiding me to search in the registry...
Have found the way to do it

I can actually get the path from
'HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Paths\';

Thanks anyway
