Installshield Setup Inx Access

Cause: The target machine lacks the necessary InstallShield runtime files.

Solution:
Deploy using Setup.exe (not MSI directly) and ensure the ISSetupPrerequisites folder is accessible. Alternatively, run:

Setup.exe /s /f1"setup.inx" /sms

/sms forces the installer to extract prerequisites to a local cache before running. Installshield Setup Inx

Instead of repeating "C:\Program Files\MyApp", the script references STRING_INDEX_45. This reduces file size and allows for easy localization (you can have multiple .INX files for different languages). /sms forces the installer to extract prerequisites to
