How to make a installer for InDesign extension

Your on the wrong forum for this but..

1) Good for a custom made extension but not for mass distribution. Tell the client to unzip and plonk it in the correct folder.

2) Slightly more graceful script the above. see my Mac version below.

3) Tell them to download an installer from http://zxpinstaller.com/

3.5) You can package the installer if you don't care about ridiculously bloating the size of your extensions

4) Slightly more graceful script the above. You can have a look at GitHub - CreativeDo/ZXPInstaller: Open Source ZXP Installer for Adobe Extensions

5) See some other ideas HTML Panels Tips: #10 Packaging / ZXP Installers | Photoshop, etc.

A plain applescript sample is

tell application "Finder"
    set destinationPath to POSIX path of (((home as Unicode text) & "Library:Application Support:Adobe:CEP:extensions") as Unicode text)
    set resourcePath to quoted form of POSIX path of ((((path to me)) as Unicode text) & "Contents:Resources:InDesign_Druckbogen_Vorschau.zip")

    set unzip to "unzip -o  " & zipFile & " -d " & zipFolder
    do shell script unzip
    delay 1
    do shell script "rm " & zipFile
    if exists zp as POSIX file then
        display notification "Die InDesign Druckbogen Vorschau Erweiterung scheint erfolgreich installiert haben"
    else
        display notification "Die InDesign Druckbogen Vorschau Verlängerung Erweiterung scheint gescheitert erfolgreich installiert haben"
    end if
