Diagnosing

MiKTeX programs log their actions into the DebugView window, if you specify suitable trace options.

To install DebugView on your computer, visit the Windows Sysinternals page to download and install DebugView.

To create a program execution trace:

1. Set the environment variable MIKTEX_TRACE. Its value must be a comma-separated list of trace stream names (see the section Trace Streams in the MiKTeX manual).
2. Start DebugView.
3. Start the MiKTeX program.
