DOS application returns a Status 20 on Windows Vista

Problem Description:  
DOS application returns a Status 20.  

Problem Environment:  
Pervasive PSQL v9  
Windows Vista  

Cause of this problem:  
With Windows Vista, Pervasive Software is no longer able to support applications that require the use of a T.S.R. (Terminate Stay Ready) Requester, this includes such Btrieve Requesters as Brequest, Breqtcp, Breqnt, etc. Windows Vista users can use the Pervasive provided Win32 DOS Box Support, which is a VXD (Virtual eXtended Driver) that comes with Pervasive PSQL v9. This VXD gets loaded as part of the operating system boot-up, however, since Windows Vista limits the location where applications can place files, users are required to perform additional steps to make this program execute.  

Solution Notes:  
Configuring BTRBOX to work with Windows Vista:  
 
1. Copy the following file (from the \pvsw\bin directory) into the \windows\system32\ directory:  
BTRVDD.DLL
