Checking the licence in installation isn't that important, you need to check it on startup more so. There are ways to get software on a machine without running the formal installer, particularly with .Net apps.

There doesn't appear to be a straightforward way of including it in an MSI. What I'd do is create a custom install EXE, which includes the MSI as a resource, encrypted with the correct key, and when you are asked to enter a key, it decrypts the MSI and if it can be verified as valid (checking the first few bytes) the 'Install' button (which launches the decrypted MSI) is activated.

Of course it is trivial for someone to take a copy of the decrypted MSI once they have created it. That's not the point of install time license checks.
