Error Code: 0x80073CF9, Couldn't Install Forza Horizon 3 on PC

Swamp with the irony, I can download and play the demo with no problem at all ......

 This will be the first and last time that I will ever buy a windows store game!

Hello guyz i was facing this problem since 3 days and finally fixed it there are videos that say to add lines in cmd create folders and stuff but nothings works! I now know how hard is it to face problems/errors and here is my sollution

Here is a fix for it :

Unfortunately u must install a new windows on ur pc

1: comepletely Format drive C(or wherever u install ur windows) and then install again on c after formating

2:After windows is comeplete make sure you update it to the latest 

3:Just after that start download your game (Forza Horizon 3) But make sure you install it where you just installed your new windows 

Well thats it and it will be just fine that worked for me 100% 

Hope this fix works For you

Update: I've fixed it! For me at least, after trying for 4 hours. I downloaded it to my F:, and I noticed there is a folder called WindowsApps that I can not access, BUT IM AN ADMIN AND THE ONLY USER.

So:

1. Right click WindowsApps -> properties:

2. Click on Advanced

3)  Owner: was set to TrustedInstaller for me, so click "CHANGE"

4. In the left square, type in your user name, and then hit "Check Names",

the box than became Windows/User , hit ok on this box and any subsequent confirmations.

5. Close windows store and Run (Win+R) =>  WSReset.exe
6. Retry and the install will show "restoring user data", after about 5 minutes or so (depends on your internet speed, I see network traffic, on a 80mbps connection), it installs successfully. Even my hotwheel dlc queue went through :D 

Note: You should also be able to access the WindowsApps  Folder too :D

If that doesn't work, I think I also did this before step 1)

net stop wuauserv

rename c:\windows\SoftwareDistribution softwaredistribution.old

net start wuauserv

I am also having an issue, what is going on? Provide us an alternative way to download the game ....... I miss the old .exe installers

Still no luck, unable to download the game.

Isn't this the same as running the wsreset.exe command?

Thank you for the patient replies so far from your colleague, however if I am still unable to download the game, how can I go about obtaining a refund? If I remember correctly, Microsoft do not allow refunds for online purchases?

For us to research further, we'd like to know more information. Kindly answer the following questions:

• What is the current build and version number of your Windows 10? To check, press the Windows key, type winver, and press the Enter key. Kindly indicate as well if it is 32 bit or 64 bit.
• Can you check if your primary hard disk has more than 30% free storage?
• Is your date and time accurate? If you have incorrect Date and Time set on your computer, you’ll have issues installing applications from Windows Store.
• Have you tried changing your internet connection? If you're connected via wired connection, have you tried downloading via Wi-Fi?
• Are you using a third party antivirus software? Have you tried using Windows Defender and download Forza Horizon 3?

Meanwhile, if you haven't tried to run the Windows Store app troubleshooter, kindly do so. We also suggest that you check the licensing on Windows Store if it is synced. Follow the steps below to manually sync it:

1. Go to Windows Store
2. Press Windows Key + C
3. Open Settings
