Steps to reproduce:

1. Install an add-on which imports gui in installTasks at the module level, such as reportPasswords 1.0

Actual behavior:

NVDA crashes and a message is presented informing that NVDA needs to be running to install add-ons.

This maybe produced by a circular import related to gui.contextHelp, according to this old issue. It seems to be fixed following the suggestion provided there by @jcsteh , that is, importing gui at the onInstall() method level.

Expected behavior:

NVDA should be restarted without crashing.
