Windows Compatibility Mode

Installing certain applications on Windows Vista or Windows 7 may require installation through Windows compatibility mode. The Oracle Universal Installer (OUI) will not run successfully on these platforms so there is a requirement to run in XP compatibility mode to install the application successfully. To install an application in compatibility mode use one of the methods outlined below:
Setting Compatibility Mode Manually

To set compatibility mode before running the executable follow these steps;

1. Right click on the 'setup.exe' for the application
2. Select 'Troubleshoot Compatibility' and the 'Program Compatibility' window should open
3. Click the option 'Try recommended settings'
4. The 'Windows compatibility mode' should be set to 'Windows XP (Service Pack 2)' or 'Windows XP (Service Pack 3)'
5. Click the 'Start the program...'
6. If the 'User Account Control' window opens with the message, 'Do you want to allow the following program from an unknown publisher to make changes to this computer?', select 'Yes'
7. The 'Oracle Universal Installer' window should now open allowing installation of the application

However, they got the following error.
