Cannot Install Office 365-Error Code: 30015-2030 (13)

Hello, I have seen the "solutions" for this and none of them work searching at the folloowing link and others. (https://learn.microsoft.com/en-us/answers/questions/4376828/cannot-install-office-win-11-error-code-30015-2030?page=2&source=docs#answers).

Reset Network Settings
Change Adaptor Settings
Running inetcpl.cpl and checking the TLS boxes.
Ran Microsoft 365 Uninstall troubleshooter: No other installs present
Ran Microsoft 365 Setup troubleshooter. Troubleshooter got stuck on "Installing Microsoft 365" and never did anything. It was running for over 30 minutes and I shut it down. Nothing was installed.
Created a Temp folder in Local disk C:, put the Office Setup. exe file in the folder and ran as Administrator. Same error.
I tried the Office Offline Installer and get the same error code after opening the drive and choosing the Setup64 icon and Run as Administrator.
I Switched networks. Internet is working fine on both.

I would think MS would fix this issue. I am running Win 11 Pro 25H2. I have more than enough space on the drive. All Windows updates have been installed. This is a clean install after replacing the SSD C Drive. Can anyone please tell me what the magic solution is?

Error code 30015-2030 (13) indicates an Office installation failure that is not resolved by the basic network and repair steps already tried. From similar Office install and repair issues in the context, the next effective approaches are:

Fully remove any broken or partial Office installations
- Use the dedicated Office removal tool (such as o15-ctrremove.diagcab or the Support and Recovery Assistant scenario for uninstalling Office) to completely remove all Microsoft 365/Office components.
- If the automated tool reports success but Office still will not install, manually remove residual Office folders as done in similar resolved cases:
  - Delete remaining Office-related folders under C:\Program Files\Microsoft Office\ and C:\Program Files (x86)\Microsoft Office\ (if present).
- Restart Windows after removal.
Ensure there is a valid Microsoft 365 license on the account
- Sign in to the Microsoft 365 account and confirm that a Microsoft 365 for home or business product is actually assigned. If there is no valid product or license, the install can fail or not present a proper install option.
- If no license is present, contact the Microsoft 365 admin or purchase/assign the correct license, then retry the installation.
Use the offline installer to bypass network/CDN issues
- Download and use the Microsoft 365 offline installer instead of the standard web installer. This is specifically recommended when normal installs fail due to proxy, firewall, antivirus, or other connection issues.
- Follow the steps in “Use the Office offline installer” for the correct Office/Microsoft 365 version, then run the installer again on Windows 11.
If installation still hangs or fails
- Confirm there is sufficient free disk space on the system drive.
- After confirming removal and license, and after trying the offline installer, if the error persists, contact Microsoft Support so they can use the removal tool plus manual cleanup (including registry and residual folders) as in the referenced resolved cases, then reinstall from the account page.

These steps combine complete removal of corrupted remnants, license verification, and use of the offline installer, which are the main patterns in successful resolutions for persistent Office 365 install errors on Windows 11.
