Problem: ArcView 9 installation fails to register modules. Installation cannot continue.

Reason: A new feature that comes with WindowsXP Service Pack 2 called DEP (Data Execution Prevention) is not allowing these modules to be registered.

Solution: You must first disable DEP before ArcView can be installed. In order to do this follow the steps below:

• Right-click on My Computer and select Properties.
• Click on the Advanced tab.
• Click on the third Settings button which is in the Startup and Recovery box.
• Click on the Edit button to edit the boot.ini file.
• There will be a very long line which you will find "/NoExecute=OptIn" at the end of. Change OptIn to AlwaysOff. This part at the end of the line should now read: /NoExecute=AlwaysOff
• Go to File>Save. Then save and close the dialog boxes by clicking on OK.
• Reboot your computer

To enable DEP go through these steps again but change AlwaysOff to OptIn.

Below are some screen shots of the steps to follow.
