I'll give that a go. But since the test verifies the creation of a workbook:
>> 3_ole.t:130: my $Book = $Excel->Workbooks->Add;
I thought it was an indication of a serious issue. But I agree, it pays to be optimistic!!
The other branch in this conversation leads me to think that the message is spurious. Win 7 Excel 10 makes an issue out of documents that are attachments to emails. They need to be enabled before you can do something to them. Maybe the under Windows 7/Excel 2010 scripts need to tell the create operation that this is a trusted operation? I don't know how to do that, but I will investigate that too in 8 hours time.
