Is there any way to find whether software installed in the system is registered by just providing the .exe file? I have tried the following code but its just displaying the directory structure in the registry. Here the code : package com.msi.intaller; import java.util.Iterator; import ca.beq.util.win32.registry.RegistryKey; import ca.beq.util.win32.registry.RootKey; public class RegistryFinder { public static void main(String... args) throws Exception { RegistryKey.initialize(RegistryFinder.class.getResource("jRe gistryKey.dll").getFile()); RegistryKey key = new RegistryKey(RootKey.HKLM, "Software\\ODBC"); for (Iterator<RegistryKey> subkeys = key.subkeys(); subkeys.hasNext();) { RegistryKey subkey = subkeys.next(); System.out.println(subkey.getName()); // You need to check here if there's anything which matches "Mozilla FireFox". } } }
