Pervasive SQL error message

I am receiving the following error from a CREATE PROCEDURE statement being executed through Pervasive.Data.SqlClient.Dll version against WGE 9.6

The statement works fine on other DSNs, and has also worked fine on this DSN until today, super.

I really need to know why this is happening, and ideally how to prevent it from randomly appearing on client machines after deployment.

The exception is thrown on the "ExecuteNonQuery()" in my code snippit.

Pervasive.Data.SqlClient.PsqlException was caught
  Message="Pervasive.Data.SqlClient.Lna.LnaException: [LNA][Pervasive][ODBC Engine Interface][Data Record Manager]Access to the requested file is denied(Btrieve Error 46)"
       at Pervasive.Data.SqlClient.Lna.LnaObject.CheckError(LnaResponse res)

       at Pervasive.Data.SqlClient.PsqlCommandImpl.doExecuteNonQuery()
       at DDInt.Common.CommonCommandImpl.ExecuteNonQuery()
       at Pervasive.Data.SqlClient.PsqlCommand.ExecuteNonQuery()

Dim cmdCreateProc As Pervasive.Data.SqlClient.PsqlCommand = m_Connection.CreateCommand()
cmdCreateProc.CommandText = strSql
If cmdCreateProc.Connection.State <> ConnectionState.Open Then cmdCreateProc.Connection.Open()

The definition of a status 46:
46: Access to the requested file is denied

The MicroKernel returns this status code for the following reasons:

    * The application opened a file in Read-only mode and tried to perform a Write operation on that file.
    * The application attempted to perform a Write operation on a file that is flagged read-only by the operating system.
    * When the application opened the file, it did not correctly specify the owner name required for updates.
    * (Workgroup engine only) If a Workgroup engine user or task opens a file that a client machine has opened using a server MicroKernel, the MicroKernel returns this status code if the Workgroup engine user attempts to write to the file.
    * (9.x and higher engines only) The application attempted to perform a Write operation on a 5.x format file. When using a 9.x or higher engine, you cannot perform a write operation such as insert or delete on a 5.x format file.

If this is happening randomly, I would guess that some other process is locking one of the Pervasive files (since you're creating a procedure it is probably PROC.DDF).  Usually, this locking can be traced back to backup or anti-virus software.  Make sure you're not scanning the PSQL data files (including DDFs) with your AV when these errors occur.

This had to do with an elusive ReadOnly flag and a seemingly inconsistent existence of ~PVSW~.LOC file which was preventing my connections from recognizing that I had turned off the silly ReadOnly flag a hundred years ago!    :)

Anyway, turn off ReadOnlys, restart Pervasive Engine, life is good.
