Fred,
User installing a product bundled with UltiDev Cassini has to have administrative rights (or be able to get elevated into Administrator account in Vista) because our Cassini installs as a windows service. Non-admin user may not be able to install UltiDev Cassini on any version of Windows.
Since you are building an installer using InstallShield, as long as your installer process is called Setup.exe, Vista will automatically elevate current user account into Admin mode (if user can be an Administrator).
Unfortunately it is impossible to change target path with UltiDev Cassini installation, nor can we make a quick change to the released product unless you have Consulting Agreement with UltiDev.
Regards,
UltiDev Team.
