Hello, I am an Eikon user. I am developing an application using the .NET API. I have a requirement to check if Eikon is installed on user machine. This is to set the market data source as users may have other sources.
Upgrade from Eikon -> Workspace. Learn about programming differences.
For a deeper look into our Eikon Data API, look into:

You can write a .NET application to get a list of installed programs. I found one solution in the StackOverflow.
My code is:
public void FindEikonOnHKCU()
{
Console.WriteLine("\nFind Eikon on the HKCU\n=================");
string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using (Microsoft.Win32.RegistryKey key = Registry.CurrentUser.OpenSubKey(registry_key))
{
foreach (string subkey_name in key.GetSubKeyNames())
{
using (RegistryKey subkey = key.OpenSubKey(subkey_name))
{
if (subkey.GetValue("DisplayName") != null)
{
var name = subkey.GetValue("DisplayName").ToString();
if (name.Contains("Eikon"))
{
Console.WriteLine(subkey.GetValue("DisplayName"));
}
}
}
}
}
}
public void FindEikonOnHKLM()
{
Console.WriteLine("\nFind Eikon on the HKLM\n=================");
//string registry_key = @"SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using (Microsoft.Win32.RegistryKey key = Registry.LocalMachine.OpenSubKey(registry_key))
{
foreach (string subkey_name in key.GetSubKeyNames())
{
using (RegistryKey subkey = key.OpenSubKey(subkey_name))
{
if (subkey.GetValue("DisplayName") != null)
{
var name = subkey.GetValue("DisplayName").ToString();
if (name.Contains("Eikon"))
{
Console.WriteLine(subkey.GetValue("DisplayName"));
}
}
}
}
}
}
It looks for the Eikon application in the SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall key of the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER registries.
