After running jmeter.bat command under Windows 7 with cmd the following error is produced:
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
Windows 7 64-bit
The work around is to login as the administrator and create the key HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs.
以管理员身份登录，创建HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs项
