@Palaniyappan thanks for quick reply
i tried those but still facing the same issue, even reinstalled the uipath along with .net 4.8 framework

Anyone got solution for this problem? I am stuck on it from last couple of days. I have tried re installation as well as .Net framework upgrade.

i didn’t get any solution, i updated the uipath to latest version

But for me upgrading to latest version caused this problem. What version you are using ?

i am using 2019.6

I have upgraded to this version and started facing this problem.

Does anybody had a chance to find the solution for this

Hi @pavan41,
Many issues related to ntdll.dll are related to corrupted windows update. There two steps you could try to do:

  1. Go to windows update in control panel and be sure that you have the newest possible windows updates.
  2. Open CMD as an administrator and type this in command prompt:
  • regsvr32.exe /u ntdll.dll and press Enter key (this will uninstall the file)
  • regsvr32.exe ntdll.dll and press Enter key (this will reinstall the file) .

Hi guys,
Does anybody fixed this issue?
