SetRegistrationCode Causes IIS to Generate a Memory Error

Toolkit attempted to read or write protected memory.

Probable Cause

This is often an indication that other memory is corrupt.

Error example:

at APToolkitNET.ToolkitWrapper.APTK_GetPropertyVDSSI(int32 zToolkit, Boolean isAnsi, Int32 zObjectPointers, Int32 propType, String stringValue1, String stringValue2, Int16 shortValue) at APToolkitNET.ToolkitSetRegistrationCode(String UserString, String LicenseKey) at IRS.DataAccess.Equipment.PrintAgreements.ToolkitRegistration()


To solve this problem, enable 32-bit applications in your Internet Information Services (IIS) Manager.

  1. Go to the IIS Manager:

    Control Panel > System and Security > Administration Tools > Internet Information Services (IIS) Manager

  2. In the IIS Manager, in the far left Connections pane, click on the sign and select Application Pools.

  3. In the main Application Pools pane that displays, right click on the application pool and select Advanced Settings.

  4. In the Advanced Settings dialog box, in the top General section, select Enable 32-Bit Applications, and set to True.
