If you receive an error message saying AccessViolationException when you try to print:
1. Confirm security is applied correctly
2. Copy A4WCRINTEROP.DLL from the Sage 300 Runtime folder
3. Paste to the Field Portal 1.1 or 2.0 \WebSite\BIN folder
4. Retry printing
This has to be reapplied later if this file is changed by Sage as part of a Product update.
