Visual Studio Community 2015 RC Installation taking too long time

Question

I've downloaded visual studio 2015 RC .iso and started installation. But It is taking too long time. It is around 20 hours of installation time but still it is not complete.

My machine is with intel i5 440 processor and 8GB of RAM. But still it is taking this much time.

Please note. I've selected all option in Visual Studio Community 2015 RC Installation ( Full Install )

Can anybody tell me the reason for this much amount of time?

Solution

Simplist possible problem is that the installer has lost it's internet connection. The lovely team at MS reponsible for this installer for VS Community 2015 did not program in an error message if the internet connection is lost. It simply won't do anything, forever if it still needs to download. Once the internet connection is re-established, it'll happily download and installer some more. Horrible oversight.
