HAL's Race Results Mk.1 was based on the Microsoft Access database management software. The last Mk.1 version was 8.19 released in 2008. HAL Mk.1 has been superseded by the Mk.2 version.
HAL Mk.2 is completely compatible with HAL Mk.1. You can load an archive file made with Mk.1 into the Mk.2 program. All your data will transfer across. There is no backwards compatibility, though. HAL Mk.2 cannot make archive files that can be read into HAL Mk.1.
If you have HAL Mk.1 loaded on your computer you can, of course, continue to use it. But the author can no longer support it and will not develop it further. If your club is committed to using Mk.1 and wants to put it onto a new computer that is possible, but it may not work correctly with versions of Microsoft Access after the 2003 release. To install the Mk.1 version do the following:
If you are still using HAL Mk.1 you should definitely consider changing to HAL MK.2 at a convenient time in your club's sailing calendar. The Mk.2 program has all the capabilities of Mk.1 and a lot more and you can transfer your data without losing anything.
