During the installation if you think it has hung (notably during the "Android SDK Setup"), browse to your %temp% directory and order by "Date modified" (descending), there should be a bunch of log files created by the installer.

The one for the "Android SDK Setup" will be named "AndroidSDK_SI.log" (or similar).

Open the file and got to the end of it (Ctrl+End), this should indicate the progress of the current file that is being downloaded.

i.e: "(80%, 349 KiB/s, 99 seconds left)"

Reopening the file, again going to the end, you should see further indication that the download has progressed (or you could just track the modified timestamp of the file [in minutes]).

i.e: "(99%, 351 KiB/s, 1 seconds left)"

Unfortunately, the installer doesn't indicate this progress (it's running in a separate "Java.exe" process, used by the Android SDK).

This seems like a rather long-winded way to check what's happening but does give an indication that the installer hasn't hung and is doing something, albeit very slowly.
