The most likely reasons DeltaWalker would not start after you have installed or unzipped it are:
DeltaWalker requires a suitable Java 2 Platform to run. If no such JVM is installed on your machine, DeltaWalker will show a message box alerting you to this fact.

Make sure your software and hardware configuration are among the ones DeltaWalker is certified to run on, as listed in the DeltaWalker Reference Platforms. For instance, DeltaWalker will not run on Windows 95.
If you in downloaded and installed DeltaWalker for Linux, you need to make sure that your Linux distribution has a correctly installed GTK+ 2.1.1 or higher.
