Check if a registry key and value exists. The key does not use 32-bit redirection on a 64-bit OS (no Wow6432Node subkey). The key and value must both be checked for existence because parsing will fail if either does not exist. (If this code is used together with other relevance code, the entire operation would return not relevant if any portion of the parsing fails.)
