@janvankuijk. Thanks for providing your feedback. I am sorry that you encountered an error. Are you installing on Joomla 4 or 3.10? Please let me know what triggered that error. I will be more than happy to fix it right away.
By the way, I just had to replace the Version 3.6 installation package file, because the wrong file was uploaded to my server last night. It was a deployment mixup in my scripts. Anyways, the correct file is there now. If you installed 3.6, then please re-download and re-install it.
