To shed some additional light on this topic, I'm incapable of outputting to Excel more than one Excel sheet's worth of information at a time.

If I load of the report generator with 5 lines of data (say 5 different restraint summaries for different load cases, as opposed to everything in one restraint summary), I'll get 5 instances of Excel, but only one instance of excel will be open on my desktop, and it'll show only the results of the last line attempted to be output.

Further, I've since had to change my command to taskkill /IM /F "EXCEL.EXE" to forcefully kill Excel.

The only additional information I have right now is that Windows (7) Updates were pushed to my machine recently, though I'm supposed to be getting a new machine in three weeks, anyways. So who knows if this'll be a non-issue or not.
