Due to the way that certain zipping programs unzip files, you may have an extra level of folders inside the installation directories.

Your folders may look like: C:\ProgramData\QlikTech\QlikViewServer\Extensions\Objects\QlikMaps_For_MQ_Points\QlikMaps_For_MQ_Points. In this case, QlikView will not be able to properly read the QlikMaps files, and will display the "Unknown Chart Type" error when attempting to show QlikMaps objects.

A quick way to validate if QlikMaps has been installed incorrectly is to navigate to http://<servername>/QvAJAXZfc/QvsViewClient.aspx?public=only&name=Extensions/QlikMaps_For_MQ_Polygons/Icon.png . If the URL should return a QlikMaps icon as it is shown in the example above. If instead

<result><message text="Empty response" /></result>

is shown, it is likely that QlikMaps has been installed incorrectly.

To resolve this, copy the innermost folder and paste to the /Extensions/Objects directory. The ending directory structure should look like: C:\ProgramData\QlikTech\QlikViewServer\Extensions\Objects\QlikMaps_For_MQ_Points. The files should be directly inside each folder, rather than inside an additional QlikMaps folder.
