Hi, I found a problem when I run a minor upgrade. I made a multilingual installshield msi project(Japanese and English) . And the default language in project is English. I built two versions of this project. Firstly I installed one version in Japanese, and the log and messages worked fine in Japanese. Then I run another version, a Japanese message like "whether I will do upgrade..." showed, and I selected Yes. By far, everything was OK. but when I checked the log, the content in log was in English! And the messages showed in minor upgrade were also in English!（I used msiprocessmessage function to show message）. When upgrade, the value of ProductLanguage property was 1033(Englsih) and the SELECTED_LANGUAGE was 2052(Japanese).
Does somebody know why ProductLanguage and SELECTED_LANGUAGE are different in minor upgrade? I would like to log in Japanese and show japanese messages in minor upgrade after the japanese version was installed. I will appreciate for your help and sorry for my pool english.
