Make sure the cryptographic service is running properly o
this computer. Please help me, tell me what is the cause

Hi

Your Cryptographic Service is most likely running fine, renaming or deleting
the Catroot2 folder is most likely what you need to do to solve the problem.

The Catroot2 problem can be avoided in the future by installing Q817287.
