I have an installer for my application which support 8 different languages. This installer is of Major Upgrade type. When I install the version X on my machine in language L1, and then I upgrade it to X+1 in L2 language; I see some part of installation UI in L1 language and some in L2 language. Is this installer behavior (because Major upgrade first uninstalls in L1 language and installs new one in L2 language) or some bug in my installer file?
