Answer 1

First of all, I suspect the HRESULT was really 0x800A03EC (it's kinda important to communicate the exact number if you are talking error codes ;-)).

What this error usually means is that one or more formula contains an error. The main reason for a formula working on one machine and not on others is usually "locale": check if that machine has different formatting settings for numbers, dates and/or currencies (comma v.s. period, etc).
