Microsoft Visual Studio Professional 2019

I created an offline installer for Visual Studio Professional 2019 (manually installing missing certificates, etc.)

I installed it offline.

After installation, I am trying to activate it offline.

Visual Studio Subscriptions

① I obtained a product key from the website and am trying to register it.

The "Your Product Key" section on the subscription site has static product keys assigned to the following two items:

② Visual Studio Express 2010 for Visual Web Developer

③ SQL Server 2000 Reporting Services Developer Edition

For ①, when I enter ② and ③ in the Visual Studio Help > Product Key Activation screen,

I get the message "Invalid Product Key" and the activation fails.

What do I need to do to complete product key activation?

Thanks for reaching out !
To activate Visual Studio Professional 2019 offline, follow these steps:

1.The key must be specifically for Visual Studio Professional 2019. If the subscription portal does not list a valid key for this edition, contact Microsoft support to verify or request the correct key. 
2. Right-click the Visual Studio shortcut and select “Run as administrator”. Go to File > Account Settings >               Unlock with a Product Key.
3. If you're using command-line installation with --productKey , ensure the key is entered as a continuous 25-character string without dashes (e.g., xxxxxxxxxxxxxxxxxxxxx).
4. Ensure you're not using a pre-release version, which does not support product key activation and requires sign-in.

    I followed your advice and contacted Microsoft support, and the problem was resolved.

    It took me a while to find the contact information for subscriptions.

    The documentation was complicated, and it was difficult to find the answer.

    Your advice was very helpful, and I'm very grateful.
