arithmetic result exceeded 32 bits

My desktop is running Windows 7 Pro, same "arithmetic result exceeded 32 bits" error whenever doing else then using the default search fields:
*not able to save searches
*not able to delete selected items
*etc.

I reside in The Netherlands and on the desktop the OS was new installed, as is X1 Search version 8.4.1.

Please analyse this issue, it seems everyone is suffering from this
