Hi Changdong,
Thanks for reaching out. You should now be able to see the Download link at the very top of the forum.
Due to a high volume of spam, I have implemented a filter for registered users. Although your account was created in 2018, it remained in a "Pending" category because you had not yet posted on the 3DNA Forum. Once a user's first post is approved, the Download link becomes visible automatically.
Best regards,
Xiang-Jun
