Hi, i'm trying to generate a sha1 hash so I can verify the integrity of a downloaded installer before I run it.
It's instructions say to run certutil -- https://wiki.gnupg.org/Gpg4win/CheckIntegrity
But when I do it fails:
C:\Users\roger\Downloads>certutil -hashfile gpg4win-3.0.3.exe sha1
CertUtil: -hashfile command FAILED: 0xd00000bb (-805306181)
When i searched by the error message i did not find much help.
Help please. I am running Windows 7 Pro with Service Pack 1.
Any ideas on how to make it work?
