After running a clemb command under Windows 7 with Modeler 14.1 the following error is produced:

java.util.prefs.WindowsPreferences <init> 
WARNING: Could not open/create prefs root node SoftwareJavaSoftPrefs 
at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Cause

The error occurs because java.util.prefs.WindowsPreferences is trying to save information in HKEY_LOCAL_MACHINESoftwareJavaSoftPrefs instead of under HKEY_CURRENT_USERSoftwareJavaSoftPrefs.

java.util.prefs.WindowsPreferences需要保存信息到HKEY_LOCAL_MACHINESoftwareJavaSoftPrefs而不是HKEY_CURRENT_USERSoftwareJavaSoftPrefs。

Environment

Windows 7 64-bit

Resolving the problem

The work around is to login as the administrator and create the key HKEY_LOCAL_MACHINESoftwareJavaSoftPrefs.

以管理员身份登录，创建 HKEY_LOCAL_MACHINESoftwareJavaSoftPrefs项

虽然Jmeter不会保存任何东西到该项，仍会将信息保存到HKEY_LOCAL_MACHINESoftwareJavaSoftPrefs。
