Can't install on Xampp

I’ve tried to install this plugin to test on my local version but it tells me it can’t create the folders. It looks like there are too many folders, ie it goes too deep. When I tried to create the folders manually (from the error list) I got all the way to the last folder and then Windows would not let me go further. Is there any way around this?
