Before you start using MemSpy, check the following items:
If you are importing log files from a disk, there are no prerequisites.
If you are importing log files from a target device, check that you have a TraceCore connection from the target device to the PC.
The MemSpy connection to a target device uses the MemSpy Launcher application that runs in the background in the device. The Launcher application is delivered with the MemSpy Carbide.c++ Extension as an RnD signed SIS file that is located in the plugins\com.nokia.s60tools.memspy.trace_X.Y.Z\Launcher.binaries folder in the Carbide.c++ installation folder in which X.Y.Z is plugin version number.
In addition, note that USB tracing requires that you have a tracing application such as TraceCoreUserApp or TraceSwitch installed in your target device.
