Q: How do I run Windows Installer?
A: Use the ShellExec function to start installation of the specified MSI file. The installer will start automatically:
ShellExec(‘’, ‘MyFile.msi’, ‘’, ‘’, 0);
Before starting it you can check if the Windows Installer is installed at the computer of the end user. If it is not installed, you can use the technique described in the .NET Framework installation question.
Q: How can I let the user open a Web page during the installation?A: Use ShellExec function and pass the URL to it:
ShellExec(‘’, ‘http://www.mycompany.com’, ‘’, ‘’, 0);
Q: How do I stop a service before a file is copied?A: Call the SvcStop function before the call to the DeployFiles function:
procedure TMyPackage.ExecSetupAction(Sender: TObject);
begin
SvcStop(‘MyService’, 60000);
DeployFiles;
end;
Or do it in a separate installation Action which executes before the Action which copies the files.
