Installing the BlackBerry PlayBook SDK will fail on Windows 7 if a 64-bit JVM is installed on the system with an error saying “Win64 not supported”.
An easy way to get the SDK to install is to force the installer to use a 32-bit JDK. This can be done by unzipping the installer. When unzipped, there are two folders (InstallerData and Windows) that are extracted. Inside the Windows folder, edit the file BlackBerryTabletSDK-Air-Installer-0.9.0.201010221500.lax Inside this file is a line that reads:
Edit this line to point to the javaw.exe executable in a 32-bit JVM you have installed. e.g.
Once you have done that, run the installer (BlackBerryTabletSDK-Air-Installer-0.9.0.201010221500.exe) from the Windows directory and the SDK will install correctly on 64-bit Windows.
