Since this is not an official PortableApp the PortableApps installer must be download first. Navigate to https://github.com/uroesch/MattermostPortable/releases for a selection of releases.
After downloading the .paf.exe installer navigate to your PortableApps.com
platform Apps Menu ❶ and select Install a new app (paf.exe) ❷.
From the dialog choose the previously downloaded .paf.exe file. ❸
After a short while the installation dialog will appear.
