The Configuration Module in the "original 5.20" wouldn't run on a 64-bit machine. This was corrected in the 1st build to 5.20.

During the Installation, the Configuration Module is invoked and the "master configuration file" is saved to the \system directory. Subsequently, any use of the Configuration Module writes the configuration file to the "current data directory".

Notes:
1) The original release of Version 5.20 is dated 090430. If this is the date of your DVD, this is your problem.

2) If you are not receiving notices when new builds are available (there were 4 builds/patches to Version 5.20) then you need to register your software. This is the only way we can e-mail important notices to you.
