Portable App Development

In my special case I would like to exclude "JavaPortableLauncher"
It does severe problems.

Hi, I'm trying to create an NSIS compiled executable that selecting it from the "open with" choices opens the designated file in a specific executable. Basically a sort of launcher similar to the PA.c launcher but without including any code belonging to it. I noticed that the PA.c Template has "FileTypeCommandLine" and "FileTypeCommandLine-extension", is it possible to implement such a thing in a .nsi script?

I explain better

EXAMPLE:

Everything I have read online says that you should start with a "clean install" of the OS in order to begin to create a portable app.

I understand the reasons why, but obviously this is not necessarily an easy thing to do for a normal user.

So my question is can you use something like VMware to create a virtual machine with a freshly installed OS and create a portable app on a computer that is not a fresh install?

If so:

I download the start(PortableAppsStartSource21.2.2.7z) source code from SF, and want to modify and customize it.
It seems the code is in Pascal, and I installed the Lazarus IDE, but it doesn't know the source code project.

What is the IDE is used to compile the code? Any guide to build it?

I downloaded LibreOfficePortable_7.3.2_MultilingualAll.paf.exe and installed it to a folder AppsPortable\LibreOffice
The installation was successful, but after that none of the applications can execute - all of them start and terminate immediately. I didn't expect such a strange problem. I didn't have that problem with LibreOfficePortable_7.3.1_MultilingualAll.paf.exe

Is it possible to exclude one of the apps from auto updating??

Generally I am happy to auto update all of the apps on startup but one of the apps I would prefer to keep at certain version and NOT update it... (higher versions are causing issues)

Must my app support Windows 7 and Windows 8?

If no, how can I document that those OSes are not supported?

I am trying to build a PortableApp.
The installer is an online installer.

The download file is an EXE file which has a folder within named $PLUGINSDIR which has a file named app-64.7z inside it.
What I want is to be able to extract the contents of app-64.7z into App\AppName folder.

Hence I created installer.ini as following:

Hey!

I did the Zotero App that was released on april 12th. I have a question, that I am a bit too afraid to ask...
Before official release, I did update my app on my Github repo. Now that Zotero is officially supported by portableapps, how do I update it?

Thanks a lot!

Hi all,
Creating my first portable app .. im stuck on the bit in the app documentation that says ...

"Start is the command line to execute to start the app relative to the AppNamePortable directory. This will typically be AppNamePortable.exe."

How do I make the .exe file?? and how does it point to the actual executable in the App\Appname\ directory?
I have a .bat file that works perfectly, I just cant figure out how to create the .exe file ...

Thanks
