Description:
There is no practical way to switch over to the debug version of MyODBC

According to the manual:

' The easiest way to do this is to get myodbc3d.dll (or myodbcd.dll) from the MyODBC 3.51 distribution and copy it over the myodbc3.dll (or myodbc.dll), which is probably in your C:\windows\system32 or C:\winnt\system32 directory.'

Unfortunately, the MyODBC DLL is in use, so I can't delete or rename it. It's possible I  could free it by deleting all the MyODBC DSNs, then rebooting, but I haven't been game to try that.  The only other way would be to boot off a different system disk, which in my case would mean pulling the hard disk out of the server and installing it in another machine.

How to repeat:
Try to delete C:\windows\system32\myodbc.dll

Perhaps you could add a debug option to the installer script.

The rename and delete file while it is in use is a Windows behavior.
Then today the only option you have is to stop all the aplications
that are using the Connector/ODBC driver.
