Maybe somebody should reach out to BellaOnline.
She is the only member I know of that has used a windows server from the get go.
In fact I think she still uses a windows server.
Her site shows she is using UBB 7.7.3 I believe.

She may have run into the path issue herself in the past.
Might save some troubleshooting steps for all.
