I have downloaded Ubuntu 12.04.2 64 bit, and I tried to install it with WUBI. I put the ubuntu ISO and WUBI in the same folder. When I installed it with WUBI, it starts downloading ubuntu-12.04.2-wubi-amd64.tar.xz, which took nearly 2 hours because my internet connection is slow.
I didn't face this problem with previous versions of Ubuntu.
How can I avoid this issue? Is there a version of WUBI that can support ubuntu-12.04.2-desktop-amd64.iso with previous version of Ubuntu?
