[Jan Richter (JIRA)]

Jan Richter commented on JBDS-3798:
-----------------------------------

1. Go to confirm page.
2. Go back to target folder page.
3. Do something to vagrant/virtualbox that makes them unavailable
4. Go to confirm page again.
Now you should get both options for the component you've disabled and the 'use existing' is broken.

> Installer detects existing tools on confirmation page. If after that a change happens (like the user uninstalls VirtualBox) and then the user goes to the previous page and to confirm page again - the change is correctly detected, but instead of replacing the old option, there are now both options for 'install' and 'use existing'. Plus the count of detected components stays the same.
> Using the existing (no longer existing in fact) installation fails, naturally.
