I'm testing a new style of Application Template for use with the Launcher and Installer. The old 2.4 release was just the barebones file structure but includes no example config files. This is of a complete template with config files and a default launcher along with a stub EXE so you can be sure it works by default.

Introduction:Often, somebody will make a post asking for help. I wrote up a guide real quick for this poster, here. After a suggestion by r-andom, I re-posted as a forum topic. If you have a suggestion for the guide, post here. If you need help portablizing, make a new post in the Portable App Development Forum. So, without much more text, I loose the gorilla. . .

    The portable app development forum is for all development discussion related to portable apps. Feel free to ask questions on adapting the standard PortableApps NSIS-based launchers used with Portable Firefox, etc with other apps. Or with help working on any portable development project you wish. You'll find more portable apps developers here than anywhere else, so, for most questions, either someone will know outright or at least be able to point you in the right direction.

    %APPDATA% won't work in GoogleChromePortable.ini

    Submitted by Hoefer on July 11, 2018 - 6:29am


    I try to use GoogleChromePortable in a pool of virtual machines. I want to "install" ChromePortable local on the machines - but the settings and the bookmarks etc. should be in the roaming userprofiles.

    When I try to change the ProfileDirectory and the SettingsDirectory via GoogleChromePortable.ini it is not possible to set the path to %APPDATA%\Chrome.
    It is also not possible to access a homedrive (E:\).
    It is only possible to change the directory via "..\..\Users" but %USERNAME% is also not supported.

    Any further ideas? Launcher (strange) issue

    Submitted by Andhika24kd on June 28, 2018 - 7:47am

    I've recently bought a new laptop and starting to make portable apps for my personal use (again). Since my old laptop hard disk is broken, I can't backup my old portable apps from the previous laptop, but there's some issue that never happened when I tried to make portable apps on my old laptop. Every time I start generating a launcher, there will be log lines that showed something like:

    MessageBox: 16: "Error: invalid value '$0' for [Launch]:MinOS. Please refer to the Manual for valid values."

    or like:

    Firefox Start in safe mode

    I use Firefox portable version 52.2.0. I witnessed an unusual behavior:
    After forcing the closure by killing the Firefox process from task manager, next time the browser is launched it will appear in safe mode.
    Do you have any explanation for this behavior, knowing that the problem doesn’t happen systematically?

    Appicon Question

    Submitted by clickclick on June 11, 2018 - 1:46pm

    I'm new to all this and I am currently trying to portabalize an app that I have installed. I have it working and need to do more testing. I am using the 3.5.0 template. I see additional .png files along with the appicon.ico included with the template, but I only have the icon that came with the app. What is the purpose off the additional .png files and are they needed or recommended?


    help with folder overwrite

    Submitted by hypersonic on June 4, 2018 - 10:50pm

    I have an app i build from stardock that's very stab-urn with a folder it creates on documents. I placed that folder on App\DefaultData because the contents in the folder are required to function however when I launch the launcher two folders are created inside documents one with my settings and the other with nothing inside. I did notice the blank folder says shared I tested putting my files inside the blank folder and it worked however its not controlled by the launcher.
