This error most commonly indicates an issue with DEP. To resolve this issue, you will need to disable DEP, or move your application to a system that does not support DEP in hardware and software. To disable DEP, please follow the following steps, as applicable (for your Server 2008, follow the steps for Windows 7) (revert steps also included):


How To Disable DEP in Windows XP

  * Navigate to Control Panel>System>Advanced Tab>Startup and Recovery>Settings
  * Click on edit button
  * Notepad will appear, editing boot.ini
  * Edit the entry for your OS so that '/noexecute=optin' is set to '/noexecute=AlwaysOff'
  * Restart your computer to integrate the change.

How To Disable DEP in Windows 7

  * Launch a command console 'As Administrator'
  * Execute:

bcdedit.exe /set {current} nx AlwaysOff

How To set DEP back to default in Windows 7:

  * Launch a command console 'As Administrator'
  * Execute:

bcdedit.exe /set {current} nx OptIn



How To Change DEP settings for a Specific Program
Windows 7

  * Navigate to Control Panel>System>Advanced System Settings>Advanced Tab>Performance>Settings>Data Execution Prevention Tab
  * Edit Settings as Desired

Windows XP

  * Navigate to Control Panel>System>Advanced Tab>Performance>Settings>Data Execution Prevention Tab
  * Edit Settings as Desired



How To discover current DEP setting in Windows 7 or XP:

  * Launch a command console 'As Administrator'
  * Execute (without quotes):

wmic OS Get DataExecutionPrevention_SupportPolicy

DEP setting enumeration

  * 0 = AlwaysOff DEP is disabled for all processes
  * 1 = AlwaysOn DEP is enabled for all processes
  * 2 = OptIn DEP is enabled for Windows system components and services (this is the default setting)
  * 3 = OptOut DEP is enabled for all processes except for those Administrators identified

Let me know if this does not resolve your issue.

Thank you for your reply,
unfortunately the problem is not DEP, that is already disabled in my system.

As you can see:
DataExecutionPrevention_SupportPolicy: 0

Hello,

You may try also disabling DEP in your system bios.

If that does not help, I'm afraid that there is little else I can do (other than suggest to run your application on less new hardware and software); we do not support the use of our ActiveX controls within the .NET environment (VS2008) (see our supported environments here: http://www.dart.com/ptwbs_env.aspx )
