The full error message often looks like this: “Microsoft Access was unable to initialize the Windows Registry. Rerun Microsoft Access or Microsoft Office Setup to reinstall Microsoft Access.“
This error can occur after you install or upgrade Microsoft Office or Microsoft Access, or after applying a Windows Update. To fix it, simply right-click on the “Cashbook Complete” icon on your desktop and choose “Run as Administrator”. Cashbook should then start up as normal and you should be able to continue accessing Cashbook normally from then on.
