Notes about the CER file extension:

Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The CER file type is primarily associated with 'Internet Security Certificate File'. In cryptography, a public key certificate (or identity certificate) is a certificate which uses a digital signature to bind together a public key with an identity. The certificate can be used to verify that a public key belongs to an individual. Canonical encoding rules (CER) are a restricted variant of Basic Encoding Rules for producing unequivocal transfer syntax for data structures described by ASN.1.

Cannot access CER files on windows?

When windows gives you an error message saying that it
"Cannot open CER files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

RECOMMENDED:

In both cases it is strongly recommended that you
run a free scan for registry errors.
