尝试安装或升级 DPA 数据存储区时，屏幕上显示以下错误，并且升级不会继续：

getEnable8dot3(Unknown Source)

这不是 DPA 问题，而是 Windows 注册表上缺少密钥的问题。
在您尝试安装/升级的服务器上，在命令提示符下运行以下命令：
reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\ /v NtfsDisable8dot3NameCreation

它应返回： 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
    NtfsDisable8dot3NameCreation    REG_DWORD    0x2

但是，如果返回以下内容，则表示确认存在问题：
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

REG_DWORD 0x2 密钥可以添加到 Windows 注册表中。

请与客户作系统/Windows 安全团队联系，因为可能存在阻止创建此密钥的策略。
