Why can't Igor Pro find example, help and procedure files?

In rare cases Igor is unable to find its supporting files, such as example, help and procedure files.

This manifests itself in a variety of ways:

• Help is not available because the help files can not be located. For example, the Help Topics tab of the Help Browser shows no topics and the Command Help tab shows no help for any operation or function.

• You get errors when you open an experiment that #includes WaveMetrics procedure files because Igor can not find the WaveMetrics Procedures folder.

• If you click the File menu and scroll down to the Example Experiments menu, its submenus are empty.
