Cause of Error

The most likely cause of this error is that the bit version of Excel is out of sync with the Interject Addin bit version. This will happen if the architecture type of Microsoft Excel/Office is changed (e.g. 32 and 64 bit).


If your architecture bit version of Excel/Office changes, you will need to uninstall Interject and reinstall. This should sync up the bit versions. For more information, see the following pages:
