Description: When you create a certificate using the Shift4 Certificate Generator, you need to install it on all Windows computers using a PIN Pad. If the certificate is not installed, the connection to the PIN Pad will not be able to be established. Review the below instructions for using Microsoft Management Console (MMC) to import the certificate on a computer level. (This means the certificate will work for all users that log in to this computer.)
This method can also be used to remove a certificate if needed. Some certificates will require this method if they are installed as a local machine certificate.
Note: This requires the user to be logged in as a local admin to the computer.
- Click the Start button, then type MMC, and run the MMC application.
- Next, click File > Add/Remove Snap-In.
- From the left frame, click Certificates, then click Add in the center.
- Choose Computer account and click Next.
- Choose Local Computer, then click Finish.
- MMC will return you to the Snap-Ins window. Confirm"Certificates (Local Computer)” appears under Console Root on the right side window titled: Selected snap-ins, and click OK.

Note: Select the certificate you would like to import (i.e., .cer, .crt, .pfx), then click Open. You may need to change the File Type to *.* if the certificate you are looking for is not appearing.
- Once the certificate file is located, click Open.
- Confirm the correct filename appears in the File name field, and click Next.
Select Place all Certificates in the Following Store and confirm "Trusted Root Certification Authorities" is selected.
Note: You may click Browse to locate "Trusted Root Certification Authorities" if this is not already listed as the certificate store.
- Click Next.
- Verify the correct file name and certificate store is listed and click Finish.
- Once “The import was successful” confirmation message appears, click OK.
- Confirm your certificate now appears in the window at the right.
Once the import is complete, you can close the MMC window. If it asks to save the settings, you may choose No.
