Check HKLM\Software\Borland\Database Engine\DLLPath key. When it does not exists BDE is not installed.
If you want to check for specific BDE drivers installation, use path from that key and check existing of correspoding files. See bdedeploy.txt for details.

   //BDE installed
 finally
   CloseKey;

Or better:

Add to uses BDE;
 
function BDEInstalled : boolean;
begin
 result := (dbiInit(nil) = 0)
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
 if  BDEInstalled then
   ShowMessage('BDE is installed.')
 else
   ShowMessage('BDE is not installed.')
end;
