Setting up the Android SDK on Windows 7 64bit, with a 64bit JDK / JRE is a bit less straightforward than one would expect, thankfully though the solution is quite simple. There are two settings that need to be adjusted to make this work – otherwise you’ll get an error indicating that Java can’t be found.

Step 1: Modify your PATH to include the bin folder of the JRE. Mine looks like this:

C:\Program Files\Java\jre6\bin

Step 2: Set the ANDROID_SWT variable (you’ll probably need to add it) to the \tools\lib\x86_64 folder of the Android SDK. Mine looks like this:

C:\Android\SDK\tools\lib\x86_64

With these two changes, everything seems to work as expected. Why this is required on 64bit but not 32bit I’m not sure, but this does seem to solve the problem.
