I use Windows version.It was 30 MB file.
When i double click on it it starts installing.then it ask select some packages.Finally it takes much time.I try it half day.Still not finished 1/4.so i close it.
Is there any other easy way to install it
I'll assume that what is causing you the most time is running the SDK Manager and downloading the various platform SDKs. I suspect that you are attempting to download and install all versions - try instead selecting only the SDK version(s) that you want - you can always download the others later.
The other possibility is to just try at another time; at times the servers get really busy (they seem to be busy right now!)
