Download the 64-bit codec entries here:

*** DO NOT RUN IT YET! ***

Before you do anything else, you need to backup your registry settings.

Click the Start icon, type "regedit" in the search bar and click the icon of the program that appears:

In the Registry Editor, select the "HKEY_LOCAL_MACHINE" branch

(OR if you're feeling extra scared, click Computer and backup your whole registry)

Now click File, Export

Save your registry file somewhere and either choose Selected Branch or All (for an entire registry backup) from the Range Settings

Once that has finished saving, then you can click the camstudiocodec.reg file to run it.

Then reboot your machine and see if that works.

Cheers

P.S. I do NOT have 64-bit Windows so I don't know if this will work.
