Self-deletion of Web Control after completion of experiment

By aya - 6/7/2012

One of the things we've been discussing in our lab is how to reduce drop-outs or simply refusal to do the experiment. Participants are prompted to download the Inquisit Web Control in addition to other security warnings (ex. Java).

We thought that perhaps supplying descriptions on what these downloads are for, could encourage people to do our experiment. I know that Millisecond supplies instructions on how to remove the Web Control, but could there be a way for it to 'self-destruct' after completion of an experiment?

Hi Aya,

The web control doesn't currently auto-uninstall, although if the participant uses Internet Explorer the version they download it put into a folder managed by Windows that will be automatically cleaned up if the user indicates through Windows that they want to reclaim disk space. 

There may be some technical challenges programming a control that uninstalls itself (a program can't simultaneously run and delete itself at the same time). Note that we do have an uninstaller program available that we distribute to those who ask for it. We could possibly polish it up a bit and offer it as an option on the finish page. 

Anyway, thanks for the feedback, I've added this issue to our list.
