It looks like you are on the computer root certificate store, and you need to get to the current user's certificate store.
When you open up mmc.exe, you should be at the 'console root' location. Next, you will need to open the current user's certificates. This can be done by pressing file -> 'certmgr.msc' from the top menu.
If you do not see the option 'certmgr.msc' from the file menu, you will need to add it using the snap in:
File > Add/Remove Snap-in...
Select Certificates from Snap-in > Add > My user account > Finish > Ok
And then you should be able to view the certificate.
You can also try opening 'certmgr.msc' directly from windows.
