UIAutomation and PowerShell 4.0

Feb 12, 2016 at 3:59 PM

Is there a known issue with running UIAutomation module on PowerShell 4.0?

When trying to load the module, an error occurs:

import-module : Could not load file or assembly 'file:///C:\Users...\Documents\WindowsPowerShell\Modules\uiautoma
tion\uiautomation.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
At line:1 char:1
  • import-module
  • ~~~~~~~~~~~~~
    • CategoryInfo : NotSpecified: (:) [Import-Module], FileLoadException
    • FullyQualifiedErrorId : System.IO.FileLoadException,Microsoft.PowerShell.Commands.ImportModuleCommand
I am running windows 8, powershell 4.0, uiautomation 0.8.7B3.NET40

If I use 0.8.7B3.NET35 instead and start PowerShell from cmd with -version 2.0, it works ok (same machine).

Hi JohnQuest, could it be that file UIAutomation.dll from the NET40 pack is blocked, i.e. you can see the Unblock button in properties of a file?
Sorry, I didn't notice your post earlier.

Yes, you are right. Sorry about that.
