Exception from HRESULT: 0x800401A8

Hi all.

I have detected the same problem and solved it.
What I guess is that UiPath is “too fast”; I mean; the “Excel Object” (from DLL) is not yet closed BEFORE the next operation, so you have to give UiPath a little more time in order to close the DLL Excel Object properly.
This can be achieved with a mere “WriteLine” or a couple of them (just one “before” and other “after”).

Give it a try!
