This is just a guess..but I run the K-lite Codec pack, I downloaded two version (I am on W7 Premium 64Bit system) but I downloaded the k Lite for both 64Bit installer and the 32Bit installer and I haven't had any problems (yet). I believe that some of the modules within Power Director are still 32Bit process' that are references through Power Director and it launches the relevant drivers.
I do have a hearing impairment and utilize an amplified headset system to access sound tho' in video editing.
