Hi Kadiravan,

You mean licence of the office is expired or we need to update it?

If Your MS office licence got expired, then Please reisntall and used licensed one or else deal with that popup at the time of excel opening.

Hi there,

Upon detecting this error, just “Kill Excel” it will work again. As this is caused by excel memory leak.

I agree with you opinion.
So do you have any idea for avoid this random exception.
e.g. Before run business flow, add one step to kill Excel thread in memory.

Add “Kill Process” activity before business process start and in the Process Name property, input “EXCEL”. I tried it and working well
