Return Codes -1 and -2 when using the Instant Protection PLUS 3 API

Details on all the Instant Protection PLUS 3 API errors can be found in the API Error Codes topic of the manual.

Listed below are the most common return codes:

Return Code -1 

A return value of -1 means the Instant Protection PLUS 3 API is not available.  Check the following:

1. Make sure you selected to use the API in the wizard. The checkbox can be found on the:
   1. Wrapper Settings page when wrapping
   2. File Output page when using the Instant Protection PLUS 3 DLL
2. Make sure you are not attempting to call an API function after calling WR_Close.
3. This error can also be returned when using the API through the Instant Protection PLUS 3 DLL when the DLL has been unloaded and re-loaded since initializing the API.  Some bindings will do this, and may mean you need to manually call LoadLibrary and FreeLibrary to prevent such an issue.
   

Return Code -2

A return value of -2 is only relevant when using the API with the wrapper and is the standard return value when the application is not yet wrapped.
