Extraction, but no execution
Hello, I'm trying to create something that will extract required API's and other dependencies for my other applications.. I've gotten it to extract to a temporary directory, but it will only execute (interestingly enough) after I click the installation package a second time. I'm sure there's a way for it to execute on the first attempt, so that is why I come here.

the code is

Name "neededfiles"
OutFile "execdo.exe"

; SilentInstall silent

Function .onInit
  SetSilent silent
FunctionEnd

Section

  SetOutPath $TEMP\tmpinstall
  FileOpen $TEMP\tmpinstall\2.exe w r
  Exec $TEMP\tmpinstall\1.exe
  File 1.exe
  AllowSkipFiles on
SectionEnd

Section
  SetOutPath $TEMP\tmpinstall
  Exec $TEMP\tmpinstall\2.exe
  FileOpen $TEMP\tmpinstall\2.exe w r
  File 2.exe
  AllowSkipFiles on
 SectionEnd

Now, I was reading something about .onInstSuccess, but after I put that in a function, the compiler told me that isn't a valid command. Any help would be appriciated.

Put both File instructions (File 1.exe and File 2.exe) right after the SetOutPath instruction into their respective section.

You don't add .onInstSuccess into a function, it is a callback function named Function .onInstSuccess, you may want to review the documentation though.

It doesn't execute the first time because you haven't extracted the files before you attempt to execute them. You have

Exec $TEMP\tmpinstall\1.exe
File 1.exe

but you need

File 1.exe
Exec $TEMP\tmpinstall\1.exe
