Set msi to not register in ARP

To hide it from ARP , just add this property
ARPSYSTEMCOMPONENT=1

Or registry for the ARP registry of the product:
REG_DWORD value 1

You can omit registering an application by removing the RegisterProduct Action, RegisterUser Action, PublishProduct Action, and PublishFeatures Action from the InstallExecuteSequence Table and AdvtExecuteSequence Table. All of these actions must be removed, or some trace of the application may remain in the registry. Removing all of these actions prevents the application from being listed in the Add or Remove Programs feature in Control Panel, and prevents the advertisement of the application. Removing all of these actions also prevents the application from being registered with the Windows Installer configuration data. This means that you cannot remove, repair, or reinstall the application by using the Windows Installer Command-Line Options, or the Windows Installer application programming interface (API).
