installation drupal 8.2.6 loops

Starting the installation of drupal 8.2.6 it starts with a screen in which I have choosen for ‘standard’ profile.
Saving this, I can choose for a language, saving this as well, the installation flips back to the choice for the profile (which I have already done). Iwould have expected the installation-procedure to continue with verifying the requirements. What went wrong?
