Hi, you could attempt to create the BHO object and you would detect whether the creation process returned null.

Note* I believe this only works if your BHO is marked 'safe for scripting'

Javascript below:

var control = null;
 
try
{
 
control = new ActiveXObject('ProgID');
if(control = null)
{
alert('Plugin not installed');
}
else
{
alert('Plugin Installed');
}
 
}
catch(e)
{
alert('Plugin not installed');
}

Remember to replace 'ProgId' with your unique id.

Hope this helps...
