Argument 'WindowInstance' must be an integer value.

Posted on by BruKn0ws 11

Hello all,

 

I'm creating a flow and the first part is to understand if Excel is open or not using the IF Window.

If it's open then run one sub flow, if it's not open run another sub-flow(that Launches Excel).

I'm getting error "Argument 'WindowInstance' must be an integer value."

 

Please help.

    I have this, and it works, but it is set up differently.

     

    Attach to running Excel

    On Error - Go to Subflow - Launches Excel - Go to next action

    So, above is the "On Error" screen for "Attach to Running Excel".  If it can't find what I told it to attach to, it goes to the subflow "Err_OpenMorningStarAll" which just has a single Launch Excel command, then it resumes with the rest of the original subflow.

     

    Best of luck!

    Great idea! Didn't remember using the "on error". Thank you!
