Android packaging not work

Hi devs,
My problem is in packaging section for android, however packaging for windows work like a charm.
I have done everything and downloaded sdk, ndk , jdk and ant also I have set all their paths in vars,
I tried using tadp-2.0r8-windows in extras folder, but it gives me an error that says:
Installer aborted because of error…
Error: There has been an error.
Error getting URL http://developer.download.nvidia.com/devzone/devcenter/mobile/tadp200/017/tadp_vars.txt

I’m using windows installer in windows 8.1 x64
