When trying to update your NBS Building Word Processing discs, the following error message is displayed: 'The installed version of the application could not be determined'.

Cause

The installer cannot identify where the previous version was installed on your PC or network. This only applies to the Microsoft Windows version of the NBS Building Word Processing Discs. The Mac version does not get affected by this issue.

Resolution

Uninstall the NBS Building Word Processing Discs from Control Panel and retry the installation. 

Please note that only the November discs of the Windows version of the Word Processing Discs are a full set of the clauses. So after uninstalling you need to reinstall the last November disc first then each update you have received since then in order. If you are getting the error with the November disc this step is not required.
