What is the default installlevel for windows installer?
If you do not provide any install开发者_高级运维level argument to msiexec, what is the default value that the Windows Installer Framework assumes? My tests seem to indicate 1, but I can't find any documentation that corroborates this.
If no value is specified, the install level defaults to 1.
