Access denied to Powershell.exe

(Marshall Blick) #1

Hi Marshall,

Thanks for getting in touch! I’m sorry to hear you’re hitting this confusing issue. I’ve seen some issues like this in the past where a virus scanner prevents access to PowerShell. Is that a possible explanation in your scenario?

Let me know how you go or if you have any further questions going forward. :slight_smile:

Best regards,

Kenny

To follow up for others seeing similar issues, we tried white-listing just powershell.exe, then increased the scope to the entire C:\Windows\system32\WindowsPowershell\v1.0\ directory, but still experienced the problem occasionally. Now we are disabling the AV during deployments.
