Executing multiple installers/exe in one installer?

Question

I want a software installer to execute another exe/installer once the one installer finish installing. No matter which installer used (NSIS, Inno Setup etc.) to make it, I just want to do this.

Is it even possible?

You can use just [RUN] section with parameters and standard or custom Checks. Remember about setting priopriate Flags - waituntilterminated makes the installer script to wait until one launched has finished it's actions and then launcher next one.

Example:

[Files]
Source: "C:\MyInstallers\*"; DestDir: "{tmp}"; 
Flags: createallsubdirs recursesubdirs deleteafterinstall ignoreversion uninsremovereadonly 

[Run]
Filename: "{tmp}\dotnetfx35.exe"; Parameters: "/q"; 
Flags: waituntilterminated skipifdoesntexist; 
StatusMsg: "Instalacja bibliotek Microsoft .NET Framework 3.5 SP1..."; 
OnlyBelowVersion: 0,6.2.8400; Check: NET35

Filename: "{tmp}\vcredist_x86.exe"; Parameters: "/Q"; 
Flags: waituntilterminated skipifdoesntexist; 
StatusMsg: "Instalacja bibliotek Microsoft Visual C++ 2008 (x86)..."; 
Check: not Is64BitInstallMode

Filename: "{tmp}\vcredist_x64.exe"; Parameters: "/Q"; 
Flags: waituntilterminated skipifdoesntexist; 
StatusMsg: "Instalacja bibliotek Microsoft Visual C++ 2008 (x64)..."; 
Check: Is64BitInstallMode

Filename: "{tmp}\directx\DXSETUP.exe"; Parameters: "/silent"; 
Flags: waituntilterminated skipifdoesntexist; 
StatusMsg: "Instalacja bibliotek Microsoft DirectX..."

Filename: "{app}\{#MyAppExeName}"; WorkingDir: "{app}\"; 
Flags: nowait postinstall runascurrentuser skipifsilent; 
Description: "{cm:LaunchProgram,{#StringChange(MyAppName, '&', '&&')}}"
