This code will be called every time the user changes the install directory, so it shouldn&#039;t do anything crazy with [[Reference/MessageBox|MessageBox]] or the likes. If this function calls [[Reference/Abort|Abort]], the installation path in [[Reference/$INSTDIR|$INSTDIR]] is deemed invalid.<br /> <br /> Example:<br /> <br /> &lt;highlight-nsis&gt; Function .onVerifyInstDir<br /> IfFileExists $INSTDIR\Winamp.exe PathGood<br /> Abort ; if $INSTDIR is not a winamp directory, don&#039;t let us install there<br /> PathGood:<br /> FunctionEnd&lt;/highlight-nsis&gt;<br /> <br /> [[Category:Callback Functions]]</div>
