Issue/Introduction

While attempting to run Oracle Installer (OUI) for an install or an upgrade on Windows, the program hangs after all installer requirements are verified.

Resolution

Per Oracle Metalink, DocId: 384257.1, the problem is associated with the Windows Data Execution Prevention (DEP) feature.  It's prematurely killing off Oracle's Installer (OUI).  Therefore, the DEP feature needs to be turned off.  Set DEP to "AlwaysOff" (guidance provided below) and retry OUI.  Here's how:

To disable DEP, do the following:

  1. Using your favorite editor, modify the boot.ini file (typically found in C:\Windows directory).  Find the /noexecute=policy_level setting and change the policy_level value to AlwaysOff.
  2. Restart the computer.
  3. Retry the OUI

Another way would be to:

  1. Click Start, right-click My Computer, and then click Properties.
  2. Click the Advanced tab, and then click Settings under the Startup and Recovery field.
  3. In the System startup field, click Edit. The Boot.ini file opens in Notepad.
  4. In Notepad, click Find on the Edit menu.
  5. In the Find what box, type /noexecute, and then click Find Next.
  6. In the Find dialog box, click Cancel.
  7. Replace policy_level with AlwaysOff.

    WARNING Make sure that you enter the text accurately. The Boot.ini file switch should now read:
    /noexecute=AlwaysOff
  8. In Notepad, click Save on the File menu.
  9. Click OK two times.
  10. Restart the computer.
  11. Retry OUI.
