We have a client that has used our COM API based interface application with Sage since 2011. They have just upgraded to Sage 50 2021, we have recompiled our application against this PAWLegacy.dll to maintain binary compatibility, but at the Login.GetApplication method, it is returning Access_Denied.
The SDK documentation lists several possible reasons. One is that our partner Company Name and Password (which has always worked) is invalid. How can we confirm that this login remains valid?
It may be possible that this client may not have answered affirmatively to allow our application to run. How can this be reset.?
