Dispatch now works happily with 64-bit (x64) Windows. It turned out to be very simple fix once we got our hands on a copy of 64-bit Windows 7. The problem was related to the installer and not Dispatch. The root cause of the problem is this: in 64-bit Windows, applications are installed in Program Files and 32-bit applications are installed in Program Files (x86). The 'problem' was that the installer configured the ODBC Data Source to implicitly to look for the database engine files in the appropriate directory for the version of Windows where they were being installed. The problem was the installer was configured to always copy the database engine files to the Program Files directory regardless of the version of Windows. Under 32-bit Windows this was not an issue. Under 64-bit Windows this turned out to be fatal (and unintentional) oversight which made it impossible for Dispatch and the ODBC Data Source Administrator to connect to the database. |
