To Install Redgate Instant Clone, run the Instant Clone installer MSI.
Instant Clone is installed into "%programfiles(x86)%\Red Gate\Instant Clone Alpha" and as a Start Menu item.
Instant Clone should be installed on any machine on which you want to do cloning operations: Creating snapshot, cloning snapshots, etc.
If you want to just use a cloned database, you do not need to install it on that machine.
