Data Protection Advisor - 嘗試安裝或升級 DPA 時發生嚴重的 LAX 錯誤

嘗試安裝或升級 DPA 資料存放區時，螢幕上會顯示下列錯誤，且升級不會繼續：

錯誤： "Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)"

Complete Error message: Invocation of this Java Application has caused and InvocationTargetException. This application will now exit (LAX)

查看錯誤中粗體字的訊息：

getEnable8dot3(Unknown Source)

這不是 DPA 問題，而是 Windows 登錄檔上遺失金鑰的問題。
在嘗試安裝/升級的伺服器上，在命令提示符下運行以下命令：
reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\ /v NtfsDisable8dot3NameCreation

應傳回： 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
    NtfsDisable8dot3NameCreation    REG_DWORD    0x2

但是，如果返回以下內容，則確認問題：
This command resulted with the same message on both the application and datastore servers:
C:\Windows\system32>reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\ /v NtfsDisable8dot3NameCreation
 
ERROR: The system was unable to find the specified registry key or value

可將 REG_DWORD 0x2 鍵新增至 Windows 登錄檔。

請與客戶 OS/Windows 安全性團隊確認，因為可能有原則封鎖建立此金鑰。
