Resolving {src} constant does not work
<p>I see that this question already was asked years ago, but without getting a reasonable answer.</p>

<p>Why doesn't this work with <code>{src}\some.exe</code> ?</p>

<pre><code>// Launch Notepad and wait for it to terminate
// if Exec(ExpandConstant({win}\notepad.exe), '', '', SW_SHOW,
// ewWaitUntilTerminated, ResultCode) then
</code></pre>

<p>If I copy notepad.exe into my Inno Setup directory, (<code>{src}\notepad.exe</code>) it does not work.
What is the secret on <code>{src}</code>?</p>
