Fixed the "invalid machine code" error in Iris 4.0.7.

I found that there are two situations: the first case is an article posted on the Internet, and the second case is based on the first study.

1. If you forget to use the registration machine to activate and expire, you will encounter this situation:
Find the HKEY_LOCAL_MACHINE/software/acudata/Sheriff/productid in the registry, for example, "5359-8621-2429-7641-5702", and change the licencepath of this item to another directory, when you exit and start Iris, a license expiration prompt will appear, back, and use the new license (with a registration machine online ).

2. The system is repaired or overwritten.
In this case, the first method cannot be used. After the first activation with the registration machine. add an item in ini named "5359-8621-2429-7641-5702". The RC item is followed by a string of "tianshu". If it is changed to a null value, restart Iris to generate a new value.
