[TYPO3-english] femanager - Please enable fineUploader plugin

[JZ]

I tried to add the "Image" field in the Registration form of femanager (1.5.2 on Typo3 6.2.19) but I'm still getting the message "Please enable fineUploader plugin" on FE when form is loaded.

Following constant is defined
plugin.tx_femanager.settings.fineuploader = 1

Additional .js files are loaded in footer:
<script src="typo3conf/ext/femanager/Resources/Public/JavaScripts/jquery.fineuploader-3.5.0.min.js?1449929969" type="text/javascript"></script>
<script src="typo3conf/ext/femanager/Resources/Public/JavaScripts/Validation.js?1449938624" type="text/javascript"></script>
<script src="typo3conf/ext/femanager/Resources/Public/JavaScripts/Femanager.js?1449938797" type="text/javascript"></script>

No JS error in console, so I realy cannot figure out what I need to add/change.

Is fineUploader another extension I need to download from TER?

Thank you in advance for your help.
