Cant reinstall game. Error [11006] [20641] [20643]

So yesterday I had some issues with my pc and had to reinstall windows. In doing so I lost my 14 install. Well ever since then I can not get the game to reinstall. Getting error "A problem occurred while updating. Please restart Final Fantasy XIV. [11006] [20641] [20643]". I can download the launcher just fine, but when I go to install the game it will install for a little bit and then give me same error. I've done research and have tried every solution I have found. From deleting and redownloading several times, to changing dns to a jp location. Nothing has worked, and its getting beyond frustrating. Any and all help would be greatly appreciated.

Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

The issue you are describing is most associated with interference with game data. Many actions can trigger this error, such as a slow internet connection, certain security/privacy changes on the default Internet browser, an application running in the background causing interference, use of a VPN or an odd connection (EG: schools or cafes), a possible virus detected on the device, many rapid payments at once, and numerous other actions.

We advise clearing the cache/cookies/browsing data from your default web browser, disabling any web browser extensions (EG: ad-blocker) and trying again.

Delete locally saved content ('Documents' > 'My Games' folder > 'FINAL FANTASY XIV - A Realm Reborn'), if you have recently reinstalled the game there is a chance the locally saved files may be corrupted.

We also suggest resetting the connection (router/modem) you are using to connect to the Internet before trying again.

Open the control panel of the PC and go to ‘Network and Internet’. Once there select ‘Internet Options’
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"
*Make sure your fire wall or antivirus program is not interfering with the game

Lastly, check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.
Lastly, we suggest to power cycle the console and router by shutting down the PlayStation 4/Router and leaving the power supply unplugged for 5-10 minutes.
