Maybe the password is the Administrator User password on the computer that is required when you install software?
Maybe the password is the AdobeID and Password to register Lightroom with Adobe?
The page let me enter the order number and password, then I entered the "Reference Number" sent to me through email (the Chinese called "参考编号", I didn't get any other number), and every password, it's always prompt me "orders could not be found".
In addition, the phone number 800 744 0438 and 800 440 0421 could not be reached.
I can't find the download url, what should I do?
另外，Adobe的客服电话800 744 0438和800 440 0421也无法拨通。
I am just another user like yourself, so I am trying to guess at your situation.
The serial number, starting with 1160 and having 6 groups of 4 digits, would be entered into the program during the install.
The AdobeID and Adobe Password (your AdobeID may be huhubun) would be used during the purchase, and then again during the install.
It is unclear where in the purchase and install process you are.
