title: Get installation path of program installed by window installer but not seen by command line "where"
body: <p>I have an Interop Excel application, installed via Window Installer, which contains only .dlls and no executables/.exes. It is seen by both &quot;Add/Remove program&quot; and <code>wmic product get name</code> listing but not by the command <code>where</code> (refering to <a href="https://stackoverflow.com/questions/4002819/finding-the-path-of-the-program-that-will-execute-from-the-command-line-in-windo/4002828?noredirect=1#comment55352053_4002828">here</a>).</p>
  <p>I am writing a batch file to modify some files after installation. How can I get the installation path of this program in my batch file?</p>
  <p>I should also mention that although &quot;Add/Remove Program&quot; sees the program, it does not exist in</p>
  <pre><code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
  </code></pre>
