Hi,
In order to create an installation which doesn't require administrator privileges, the package must meet these conditions:
- in the "Install Parameters" page you set the "Installation Type" to "Per-User"
- in the "Files and Folders" page you make sure that all the files of your installation are placed in per-user locations
- in the "Registry" page you create keys only under HKEY_CURRENT_USER
You can read more about this here:
