Trouble to create a new presentation



I have troubles to create a new presentation. I have the following message: impossible to create a presentation. It says that I have to change some parameters in chrome but I have already done it.
I also tried to use the standalone but it says that I have to install directX. I checked, the directX 11 is already installed on my computer.
thanks for your help.
