I guess I'm just dense, but I've been to https://portableapps.com/development , https://portableapps.com/node/12851 , https://portableapps.com/node/14939 , copied the code for PortableApps.comInstaller.nsi and PortableApps.comInstallerConfig.nsh and seem to understand how to modify it.
Ok, now all I need to do is install a bunch of files in "AppNamePortable" and "App" directories. Should be the simplest script entries ever - Right?
Well, looking at other installations, as suggested, gets me nowhere. Looking at the NSIS simple examples make sense, but require editing the .nsi script. But it says "PortableApps.comInstaller.nsi which should not be edited".
I admit it. I'm lost. Help? How do I install my files, where do the instructions go to just put some stuff in his "APP" directory, and how do I end up with an ApplicationPortabple.paf.exe?
There are a lot of very interesting sophisticated questions being answered here, but I get started. It seems making the code work is simple compared to installation.
Point me at something simple? I know everyone's going to fall over laughing, but I'm getting frustrated.
