During the install of the .ppm file of update, I receive the following error message after about 10% completion:

"Re-try by running command prompt with administrative privilege to change KMP folder permission."

Attempted Solutions:

1. Added service account used for login to server's local Administrators group.

2. Gave service account Full NTFS permissions manually on folder to C:Program Files\ManageEngine\KeyManager (Home folder)

4. Granted Full NTFS permissions using command:

      icacls "C:\Program Files\ManageEngine\KeyManager" /grant <KeyManagerServiceAccountName>:(OI)(CI)F /T

Are there any suggestions that I haven't tried that may work?
