Yup, that's quite handy. Just remember to choose MicrosoftCodecPack_amd64.msi, which is the one meant for 64-bit systems. All systems that are less than a few years old are based on 64 bit architecture. To make sure, open the start meny, right click on Computer and select properties. It should say system type: 64-bit. If it says 32-bit, then MicrosoftCodecPack_x86.msi is the correct file.
