Thank you for your effort, and information. No worries, I'm not in hurry about the language issue. All we need is a stable result, and it's understandable that it requires time.

I will check more about the Uninstaller.log file location issue, and write the results soon. But could you please give me more detail about your statement, "might cause problems when updating the Add/Remove Program Panel"?

Please feel free to compile your test.exe with any ID except English (USA). Cheers
