Unable to open User Access Viewer, no error message on Windows XP

Remove data protection from the operating system:


No-execute and execute protection are all names for DEP. This process feature increases security, but may cause problems with certain programs.

Several OSs have no-execute or execute protection. Microsoft has added this as well in SP2 with data execution prevention (DEP). This precents code execution in memory regions already marked as storage. This is a powerful tool against buffer overrun exploits.

If a program is failing and you want to disable DEP to see if that is the cause. Here are the steps. (Just disable DEP for the program in question… don’t disable it for your whole system.)

    1. Click Start
    2. Select Control Panel
    3. Select System
    4. Click the Advanced tab
    5. In the Performance region select Settings
    6. Click the Data Execute tab in the dialog box that opens
    7. Select Turn on DEP for all programs and services except for those I select
    8. Click Add.
    9. The open dialog box will open. Browse and select your application.
    10. Click Open
    11. Click Apply
    12. Click Ok
    13. Reboot
