Every software (say Firefox) creates it's entry under the path
每个软件（比如 Firefox）都会在路径下创建它的条目
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Firefox also creates it under the same path. In my machine
Firefox 也在同一路径下创建它。在我的机器上
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla Firefox5.0.1(x86 en-US)
is path for that.
是路径。
Existance of this path confirms that firefox is installed on machine. For the installation directory, read the value of key named 'InstallLocation' under above mentioned path for Firefox.
此路径的存在确认机器上安装了 Firefox。对于安装目录，读取 Firefox 上面提到的路径下名为“InstallLocation”的键的值。
