I try to do upadating MikTex version 6852 10/3/2018 and receive Miktex Error Report - MikTex console:
The operation could not be completed because a required file failed verification.
package="ocgx2", arhiveFile="D:\Install\MikTeX-2.9\x64\ocgx2.tar.lzma", expectedMD5="348e2af1b8afc5ebcd057a56fa62d6d3", actualMD5="b44caab1d9910439ce557ffb2347f592"
Is this non-correct download of updating files? What can I do?
