Hi, I hope you are well

I have created a Desktop flow where I am running Claims in a legacy system and it runs perfectly fine on Attended license.

I am now trying to run it using an Unattended license and it fails when it has to run excel stages i.e Launch Excel.

Please refer to the attached picture for more context on the error.

I would really appreciate your help.

Hi,

Make instance visible: FALSE (Critical for unattended)

Option B: PowerShell Integration

Add PowerShell script action before Excel operations:

powershell

Get-Process excel -ErrorAction SilentlyContinue | Stop-Process -Force # Set Excel to run in compatibility mode $excel = New-Object -ComObject Excel.Application $excel.Visible = $false $excel.DisplayAlerts = $false $excel.ScreenUpdating = $false $excel.Quit() [System.Runtime.Interopservices.Marshal]::ReleaseComObject($excel)

If I have answered your question, please mark it as the preferred solution ✅ . If you like my response, please give it a Thumbs Up 👍. Regards, Riyaz

Hi, I had the instance visible set to off already.

I also tried option B, the script ran, but Excel stage is still failing.

What Riyaz_riz11 writes is NOT true, and it is NOT necessary or recommended.

What are you trying to launch? It looks like the filepath is empty.

Thank you so much! I realized my mistake through our engagements, so I was unaware that I have to tick the parameters and also add values.
I thought that adding the values in the flow alone is enough.
