How to allow only one Checked Box in [Run} Section?

My Innosetup program installs 3 programs during the installation.

I added the checkbox for the 3 program to show after installation page in the [Run] section:

Filename: "{app}\Program1.exe"; Description: "{cm:LaunchProgram,{#StringChange("Program1", '&', '&&')}}"; Flags: nowait postinstall skipifsilent unchecked runascurrentuser;
Filename: "{app}\Program2.exe"; Description: "{cm:LaunchProgram,{#StringChange("Program2", '&', '&&')}}"; Flags: nowait postinstall skipifsilent unchecked runascurrentuser;
Filename: "{app}\Program3.exe"; Description: "{cm:LaunchProgram,{#StringChange("Program3", '&', '&&')}}"; Flags: nowait postinstall skipifsilent unchecked runascurrentuser;

How can i make it only allow to check one box at time?

THank you
