NSIS - Radio button to select one of many programs to install - nsis

Question

I have 4 programs that I'd like to package into one installer and allow the user to select which one they would like to install.
I've never used NSIS before but I was recommended to give it a shot, however, I've no idea where to begin with this.
Basically I just need one page that asks the user to select a radio button then click next to install one of the following programs:
-- Install components --------------------
Select a program from the list below and
click Next to continue.
O Program 1
O Program 2
O Program 3
O Program 4
-------------------------------------------
Cancel Next
Then depending on what they choose it launches program1_setup.exe or program2_setup.exe etc.
As each of my 4 programs are installers in their own right, I take it I don't need to set up the uninstall script in NSIS as that's taken care of already?
Thanks,
Greg.

Answer 1

This code is similar to the one-section.nsi example.
...
!include sections.nsh
Page components
Page instfiles
Section /o "Program 1" P1
File "/oname=$pluginsdir\Setup.exe" "myfiles\Setup1.exe"
SectionEnd
Section "Program 2" P2
File "/oname=$pluginsdir\Setup.exe" "myfiles\Setup2.exe"
SectionEnd
Section ; Hidden section that runs the show
DetailPrint "Installing selected application..."
SetDetailsPrint none
ExecWait '"$pluginsdir\Setup.exe"'
SetDetailsPrint lastused
SectionEnd
Function .onInit
Initpluginsdir ; Make sure $pluginsdir exists
StrCpy $1 ${P2} ;The default
FunctionEnd
Function .onSelChange
!insertmacro StartRadioButtons $1
!insertmacro RadioButton ${P1}
!insertmacro RadioButton ${P2}
!insertmacro EndRadioButtons
FunctionEnd
You can use the CheckBitmap attribute to change the checkbox icons if you want...
