Set a new registry 'BuildType' when installing. Check for this reg key
when upgrading to a newer version. Show error message and exit
if the previous installation does not have the same 'BuildType'.
Encode the CLI version into MSI supported ProductVersion documented here -
https://msdn.microsoft.com/en-us/library/windows/desktop/aa370859(v=vs.85).aspx
Example: CLI Version - 1.0.0.000930 is encoded in MSI as 4.0.930
Prevent downgrading by failing installation with error message.
Also display the original CLI version in the ProductName.
