uninstalling with PS App Deployment Toolkit

Hello,

I’m trying to learn to use the Powershell App Deployment Toolkit to manage deployments for my organization. I’m following the excellent beginner’s tutorial provided by /u/replicajunction, but running into an issue when trying to uninstall Mozilla Firefox, as in the example in that tutorial.

I’m able to install Firefox successfully, but when I uninstall, Firefox remains on my machine. The log file lists:

[Post-Uninstallation] :: Mozilla_Firefox_47.0.1_x86_EN_01 >Uninstallation completed with exit code [0]. Exit-Script 7/22/2016 >10:56:14 AM 3412 (0x0D54)

which implies to me that the uninstallation was successful, however, Firefox remains on my computer.

For those familiar with PSADT already, this is my Deploy-Application.ps1 Pre-Uninstallation and Uninstallation blocks:

pastebin

I’m launching the uninstallation from the command line with Deploy-Application.exe Uninstall

Thanks in advance for any help you can provide.
