Flash Builder 4 official version is released. I'm glad to have the Simplified Chinese version. Go to the Adobe official website and try again.
There are many registered serial numbers on the Internet, but they have all expired.
We can use the following registration machine to generate the serial number:

However, after the registration serial number is used for the first time, it will go to the Adobe official website to verify the validity of the serial number when it is opened for the second time.
So we can let Adobe not go to the official website for verification. The method is as follows:
Add one to the C:/Windows/system32/Drivers/etc/hosts file:
127.0.0.1 activate.adobe.com
Use the registration machine to generate a registration code and register it again. After restart, the registration trial prompt will not appear again.
