Hi&nbsp;Topbuild,&nbsp;
&nbsp;
It looks like you're experiencing the&nbsp;Microsoft.Office.Interop.Excel._Application&nbsp;error.&nbsp;Generally this error means that when a program such as AccountRight asks which version of Excel is installed, the wrong version is being reported back, causing a communication problem and errors between the programs.
&nbsp;
This can happen when different versions of Office/Excel may have been previously installed on the computer, and components/values are left behind. This type of error can be fixed by one one of the following:

Quick repair office.&nbsp;(any missing files should be added back)
Check/Fix&nbsp;Registry Keys (this step can only be completed by an IT professional as this is an environmental issue with windows having missing or incorrect information). Reference link as an example for Outlook is :https://webmakers.co.nz/interface-not-registered-exception-from-hresult-0x80040155-microsoft-office-...

Please do let us know how you go.&nbsp;
