I tried blackra1n on Windows 7, but it crashed when I first tried opening it. To get blackra1n to work on Windows 7, do the following:

1. Right-click the blackra1n icon and click properties.

2. Click the Compatibility tab.

3. Under compatibility mode click the box to enable it and select Windows XP (Service Pack 2). Click OK, and then run blackra1n.
