Oracle 11g setup closes without errors on pre-requisite check

I assume you are using the 64 bit version of Oracle to install.

I assume you have Windows 7 x64 - Professional, Enterprise, or Ultimate edition

In the case of unusual errors it would not be impossible for something silly like the language pack in use on Windows to be the cause. Try starting with a new Windows install that has not been customized or has had any other Oracle products installed or removed

Check the install logs. With all the versions and folder name changes I am not 100% sure where but you should look in the c:/Windows/oracle or in the install folder if located on hard disk

The installation logs should be on the SYSTEM_DRIVE:\Program Files\Oracle\Inventory\logs

You can find some detailed information about installation troubleshooting here:

• F.3 Reviewing the Log of an Installation Session - Troubleshooting the Oracle Database Installation

If the installation logs are not enough, you can go to the Event Viewer (Control Panel\All Control Panel Items\Administrative Tools\Event Viewer) and check the System or Application folders. There has to be a track of the error.

Also, you can try to open the installer with "Run as administrator".

Uninstall if any antivirus is installed then check. I also had same problem I uninstalled antivirus and my Oracle setup got installed correctly
