installation error

[toprngr]

Can you please tell us more details about the error that you are facing here? What version are you using? I had no problems installing and running it on my computer. Might it be something that you did? Like settings, or moving files during the installation? It wouldn’t go that way if you have run it normally. Most probably that the directory is missing or it has been renamed. There is a possibility that your installer is corrupted too, you might want to download it again.
