Unable to open file for write

[linlysergel]

On many of my workflows, I keep getting the "Unable to open for write [...] The process cannot access the file because it is being used by another process (32)." when I try to write multiple tabs to the same Excel workbook.

I've tried strategically dropping my tools so that they all have sequential IDs, using the block until done tool (which I clearly don't know how to use properly), and even a parallel block on another workflow.  What am I doing wrong?
