The answer to this question can be found using the formula for the number of combinations of n items taken k at a time, which is 2^n - 1. Here, n is the number of friends, which is 6.

Step 1: Calculate 2^n, which is 2^6 = 64.
Step 2: Subtract 1 from the result to account for the case where no friends are invited. So, 64 - 1 = 63.

So, there are 63 ways to invite one or more of six friends to dinner. Therefore, the correct answer is 63.
