Uipath unable to locate Power shell

Hello Team,

I am facing a strange issue with Uipath’s Invoke Power shell Activity . When i tried running it . I am getting an error on Win 10 64 bit machine as Windows PowerShell 1.0 is not installed ,which is required by Invoke Powershell Activity.
Exception type system.InvalidOperationException .

Any help would be much appreciated .


Hi All,

I am also facing the same issue,

We have migrated a live project from version 2016.2 to 2018.4 and Invoke Power shell activity is throwing error.

Any help would be appreciated.

I have faced the same issue. I think this issue is from UiPath side. I have updated the UiPath.System.Activities package to 20.4.0, the issue get resolved.

Now for me, powershell is working fine.
