Here is the modified program:

```python
def factorial(n):
if n == 1:
return 1
else:
return n * factorial(n-1)

def product_of_even_numbers(n):
product = 1
for i in range(2, n, 2):
product *= i
return product

print("The factorial of 7 is", factorial(7))
print("The product of all the even numbers less than 7 is", product_of_even_numbers(7))
```

Output:
```
The factorial of 7 is 5040
The product of all the even numbers less than 7 is 48
```

In the modified program, a new function `product_of_even_numbers` is added to calculate the product of all the even numbers less than the given input `n`. It uses a `for` loop to iterate from 2 to `n-1` (exclusive) with a step size of 2 to only consider even numbers. The current product is multiplied by each even number in the loop. Finally, the product is returned.

To modify the program to print the product of all the even numbers less than 7, you can make the following changes:

1. Define a new function called `even_factorial` that takes an argument `num`.
2. Inside the `even_factorial` function, initialize a variable `product` to 1.
3. Use a for loop to iterate through the numbers from `num` down to 2 (exclusive) with a step size of -2.
4. Multiply each number by the `product` and update the value of `product`.
5. Finally, print the value of `product` after the loop ends.

Here's the modified code:

```python
def even_factorial(num):
product = 1
for i in range(num, 2, -2):
product *= i
print("The product of all the even numbers less than", num, "is", product)

even_factorial(7)
```

Output:
The product of all the even numbers less than 7 is 48

To modify the program to print the product of all the even numbers less than 7, you will need to make the following changes:

1. Add a new function called `product_of_evens(n)` which will calculate the product of all the even numbers less than `n`.

```python
def product_of_evens(n):
product = 1
for i in range(2, n, 2):
product *= i
return product
```

2. Inside the `print` statement, instead of calling the `factorial()` function, call the new `product_of_evens()` function.

```python
print("The product of all even numbers less than", 7, "is", product_of_evens(7))
```

With these modifications, the program will calculate and print the product of all even numbers less than 7.
