Version 1.03 In Development ... An enquiry about the program revealed the need for a re-think in the interpretation of the Total Charge Regulations provisions relating to the calculation of periods (Regulation 11). The basic view had always been that a statutory calculation could be done using either weeks, months or years and days - and only one of those should be use for all the periods in a calculation. On re-consideration, it was accepted that every individual period in a calculation should be considered on its own to see if it could be described in weeks, months or years and days. It was therefore necessary to modify DualCalc to work in this way. Unfortunately this also raised a number of other issues which needed to be considered before implementing the changes. This work has only just been completed and is still undergoing testing while the documentation is being revised. The opportunity had also been taken to introduce some further improvements to the program and modify it to deal with some issues introduced by the release of Windows Vista. This page provides a (rather cryptic) log of the changes made to the program so far and an opportunity to download the latest release candidate.

Important ... The current version: v1.03(rc6A), is not a genuine release candidate because it incorporates changes to correct discrepancies in the way dates are handled in actuarial calculations. These are, as yet, untested and the changes have not yet been paralleled in the program's output routines - so these will report the previous timing values, not those used in the calculation. Installation ... The link above only provides an executable as a direct replacement for your current DualCalc.exe, it is not an installer and none of the associated files are supplied. You are advised to keep a backup of your current copy before replacing it with the release candidate. There is currently no documentation of the changes or new features. The current release candidate assumes that, for Windows XP and Vista, the program's resources are in a folder in 'Documents and Settings\All Users\Application Data\DualCalc' (usually in C:). This should contain the folders Help, Resources, Saved, Logged and Tools which, in previous versions, were in the same folder as DualCalc.exe. This will be created and filled by the final installer but, to run the release candidate, you are advised to make this folder and copy the listed folders into it before running the release candidate. You are also advised to delete the file Setup.txt in the Resources folder and then re-save your option settings.
