Win 7 32bit reinstall failure

After a HD failure I had to reinstall my windows 7 - 32bit which had been running for many years. But now after a week or two it's now saying "Windows 7 Build 7600 This copy of Windows is not genuine" which is not true. The DVDs are all original with visually reflective Windows 7 logo and the Product Key is the original orange/white label inside. The original DVD case has the Microsoft logo with 3 different bar codes on the back with a gold stripe. Now with trying to activate Windows 7 it says to "Enter the complete installation ID which is at least 14 digits"? I cannot find what or where is this "installation ID".?.? I have spent many hours just getting this far with no human help available on the phone. What am I missing and how do I proceed?

Thanks for any help.

Why Windows 7 you may wonder? I have 2 needed old applications that will not function beyond Win 7. Sigh..

    The Installation ID is generated by Windows—not printed on the DVD or packaging—and you can display it by running SLUI 4.

    Obtain the Installation ID and activate

    1. Press Windows logo key + R.
    2. Enter:
         SLUI 4
      
    3. Select your country or region, then click Next.
    4. The Windows Activation window displays the Installation ID, normally divided into several numbered groups.
    5. Open Microsoft’s Product Activation Portal, complete the CAPTCHA, and sign in.
    6. Select Activate a Microsoft Product → Windows → Windows 7.
    7. Enter the Installation ID and submit it.
    8. The portal should return a Confirmation ID.
    9. Return to the Windows Activation window, enter that Confirmation ID, and select Activate Windows.

    This is Microsoft’s documented Windows 7 offline-activation procedure; Microsoft now directs users to the activation portal rather than the telephone number displayed by older activation screens.^1^

    Command-line alternative

    If SLUI 4 does not display the ID:

    1. Open Start, type cmd, right-click Command Prompt, and select Run as administrator.
    2. Generate the Installation ID:
         SLMGR.VBS /dti
      
    3. Submit that ID through the Product Activation Portal.
    4. After receiving the Confirmation ID, enter it without hyphens or spaces:
         SLMGR.VBS /atp YOUR_CONFIRMATION_ID
         SLMGR.VBS /dli
      

    The last command displays the resulting license status.^1^

    If the portal rejects the activation

    • Record the complete error code and message; “not genuine” alone does not identify why activation failed.
    • Check Control Panel → System and Security → System and ensure the installed Windows 7 edition exactly matches the licensed edition printed with the original copy—for example, Home Premium versus Professional. Microsoft identifies installing a different Windows version during a rebuild as a possible activation failure.^2^
    • If the edition matches but the portal will not issue a Confirmation ID, use the support options presented by the Product Activation Portal and request a manual license review. Keep the DVD packaging and product-key label available as proof of purchase.

    Windows 7 support ended on January 14, 2020, although Microsoft still publishes this activation process.^3^ Because the computer must remain on Windows 7 for legacy applications, keep it isolated from untrusted networks where practical.
