Hi,
As this is a public forum for support English, and have not any sub forum for support other language, please post and reply with English, it would be more convenient for communication.
I translate your post into English, and found you can't activate your computer after changed structure, right?
How did you change structure? As the only official way to change windows 10 pro from 32 bits to 64 is clean installation with a 64 bit installation image. So make sure you did the official measure with an valid system image.
What's your product key type? A retail key, OEM product key, upgrade from home to Pro key? or volume license key such as KMS or MAK?
Any error message occur when you try to activate with it?
Please go to search box, and type "run" to open Run box. Then type "slui.exe 4" to activate through a call.
If issue persists, please reply to us those questions for narrow down your issue.
Bests,
