Hello, nihonjintaylor
I'm a Japanese user, too.
At first, my account name doesn't include any double byte characters, i.e only alphabets.
And my account has administrator's right.
The OS is Windows XP Home SP2, and avast! built is Nov2005(4.6.731), Home Edition.
avast! was switched to English from Japanese, then I tried to open the avast's Chest.
It was opened via English Simple User Interface (SUI).
But I found something, probably.
Windowns is so tricky.
I created a new account for Windows.
This new account name has only alphabets. (It's "mt-river")
Turned off and turned a computer on, then logged in.
The chest was opened via English SUI.
I renamed this account with kanji, like "山川".
Turned off and turned a computer on, then logged in.
The chest was opened via English SUI. No problem.
Then, this account was renamed to another, "十石"
The kanji, "十", is not only a double byte character but also including a special code in Shift JIS code set used on OSs of Microsoft.
Turned off and turned a computer on, then logged in.
The chest was opened via English SUI. No problem.
The next step.
I created another new account for Windows.
This new account name includes kanji, but no alphabet. (e.g. "山川")
Turned off and turned a computer on, then logged in.
The chest was NOT opened via English SUI.
However, the chest was opened via Japanese SUI.
This account was renamed to ENGLISH one. (e.g. "mt-river")
Turned off and turned a computer on, then logged in.
The chest was NOT opened via English SUI, but Japanese SUI is OK.
When tried to open the chest via English SUI, an error dialog was appeared with this message.
