TRegistery的LoadKey这个方法更好！ function LoadKey(const Key, FileName: String): Boolean; Description Call LoadKey to: 1 Create a new subkey under the root key, and 2 Load registry information from a file into the subkey. Registry information can include data values, subkeys, and data values for those subkeys. LoadKey is intended to simplify creation of a key, its values and subkeys, and the values for those subkeys in a single operation. A key, its subkeys, and all data values of the key and its subkeys is called a hive. Rather than creating each key and value separately, an application can read a hive from a file. This is especially useful for applications that users can reconfigure at run time. Note: Before an application calls LoadKey, the RootKey property must be set to HKEY_USERS, HKEY_LOCAL_MACHINE, or to a key returned by a previous call to RegistryConnect.

用这个函数，直接调用reg文件，系统应该会自动的安装。
ShellExecute(0,nil,'a.reg',nil,nil,SW_HIDE)
