mmh.. for some reason the original post in this thread is only showing
up now in my mailbox i.e. way after Steffen's answer (and even if
Steffen's answer includes the original post, I must confess that I
didn't really pay attention to it)
Anyway, based on that original post I see now that Egon was using
download.file() but this was not working on Windows 10 so he
switched to
the RCurl solution. And the RCurl solution works on Windows 10 but now
fails on our Windows builders (Windows Server 2012 R2 Standard). Do I
get the situation right?
