Win7 64-bit under install oracle11g encounter problems and cannot remove clean issues

Today, under the Win7 installed oracle11g deleted and unloaded back and forth to restart 4, 5 times, combined with the Internet is to explain the following points:

First, Win64_11gr2_database_1of2.zip and Win64_11gr2_database_2of2.zip decompression will be the second decompression of the win64_11gr2_database_2of2\database\ All content under Stage\components is copied to the Win64_11gr2_database_1of2 folder, which is to prevent the installation package from being less problematic;

Second, all the operation should be performed with the management identity, which is the issue of Win7 permissions, specifically do not understand why

1), Win64_11gr2_database_1of2\database\setup.exe under the right mouse button select "also Run as administrator" execution setup.exe

2), CMD also to start with the administrator--All Programs--Accessories--"command Prompt"--right click to run as Administrator; Due to the Win7 permissions issue, although we are using the Administrator account, However, when you run cmd, you do not use administrator privileges, so you will have no access to the relevant directory.

Iii. oracle11g Default User and password issues

Login identity: Refers to the role specified at login, oracle11g in SYSDBA and default two kinds.

PS: In the installation of Oracle 10g, prompted to create a database, the creation of the prompt you to enter a password, if you enter a password at this time, when you log in to the database user name sys password should be entered when you create a database password. Rather than the default manager.
