:The installation directory (<code>$INSTDIR</code> is modifiable using [[Reference/StrCpy|StrCpy]], [[Reference/ReadRegStr|ReadRegStr]], [[Reference/ReadINIStr|ReadINIStr]], etc. - This could be used, for example, in the [[Reference/.onInit|.onInit function]] to do a more advanced detection of install location).<br />
:<br />
:Note that in uninstaller code, <code>$INSTDIR</code> contains the directory where the uninstaller lies. It does not necessarily contain the same value it contained in the installer. For example, if you write the uninstaller to [[Reference/$WINDIR|$WINDIR]] and the user doesn't move it, <code>$INSTDIR</code> will be <code>$WINDIR</code> in the uninstaller. If you write the uninstaller to another location, you should keep the installer's <code>$INSTDIR</code> in the registry or an alternative storing facility and read it in the uninstaller.</div>Bugmenot
