Hi Tamar,

thanks again for your script. It helped me understand some more of the coding used in InnoSetup. Now all I need to do is work out how to install a Windows Service.

In case anybody is interested, here is a simplified version of what I came up with:

#define MyAppName "Samaan Systems"
#define MyAppVerName "Samaan Systems"
#define MyAppPublisher "Samaan Systems Ltd."
#define MyAppURL "http://SamaanSystems.com"
#define MyAppExeName "myprog.exe"

[Setup]
AppName={#MyAppName}
AppVerName={#MyAppVerName}
AppId=SSL1
AppPublisher={#MyAppPublisher}
AppPublisherURL={#MyAppURL}
AppSupportURL={#MyAppURL}
AppUpdatesURL={#MyAppURL}
DefaultDirName={pf}\{#MyAppName}
AppVersion=1.0
DefaultGroupName={#MyAppVerName}
Compression=lzma
SolidCompression=true
OutputBaseFilename={#MyAppName} setup
CreateAppDir=no
LicenseFile=readme.txt
DisableProgramGroupPage=yes

>>Hi,
>>
>>My installation needs to give the user the option of doing a workstation install, a shared file install or a full install (workstation and shared files). Using my current script, the user is first prompted for the directory to install the workstation files in, then the component selection page gets displayed. I'd like to display the components selection page first, then if the workstation or the full installation has been selected display the screen to select where to install the workstation files.
