I am quite new to Inno Setup. I am currently compiling an installer for my .exe and I have come to know that ShellExec and Exec (File Functions) allows me execute 3rd-party installers.
May I know what are the available value(s) or string(s) for 'Params' input of both these functions? At the moment, I only know /S is for silent install (hide the 3rd-party install window). Any resource(s)/cheatlists/cheatsheet(s) on this is greatly appreciated. I am not sure where to refer to on this because their documentation on those two File Functions did not explain on it.
Inno Setup Documentation (File Functions): https://jrsoftware.org/ishelp/index.php?topic=scriptfunctions
The "params" are specific to the third-party installers. You didn't tell us anything about them.
Though the /S is used by NSIS-made installers. For NSIS commandline parameters, see:
https://nsis.sourceforge.io/Docs/Chapter3.html#installerusagecommon
Though it's quite possible that even other installers use /S.
In general running an installer (or any program) with /? (or -?, /h, /help, etc) should give you commandline help.
