Can you clarify where it says that? Does this message appear in-game or on our website?
Unfortunately the only way we can check that you actually own the game is through this in-game verification. Emails or order details from Microsoft cannot be verified from our end.
It appears in-game when I am playing it. Please fix this. Unless there is a way to mod Windows 8 version, this is very annoying!
It’s definitely working on our test machines and we haven’t really seen this issue before.
Are you sure that you are logged in with the same user that purchased the game?
Do you have any other issues using the Windows Store?
Well, I assume I am knowing that when I go to install the game it says I have already purchased it. I do not have any other issues and I just did a wsreset,exe(resets the Windows Store) and it still does not work. Is there a way I need to log onto the game? I can double check but I should/better be logged onto the account that still has the e-mail of the Microsoft receipt. And if a link shows but, couldn’t you just copy and paste the link for me to go to?
EDIT: Here is what it said EXACTLY.
“Could not verify App Receipt from Windows Store”
“Gateway Time-out”
"If the issue persists report this error to support@greenheartgames.com"
That is what it said and I quote. But I also tried signing in and out and it still didn’t work. I hope there is a fix somehow…
Maybe there is a problem communicating with our server. Are you sure that the game has internet access and isn’t blocked by a firewall or some proxy server?
How do I check if the game has internet access? And my firewall is disabled but I do not know much about proxy servers so I am not sure about that one. But 1, how do I check if the game has internet access? And 2, can you allow apps through a proxy server in Google Chrome or does it have to be in system files through your OS?
As a quick check, can you access the following site?
http://customers.greenheartgames.com/ (try to open it in win8.1 IE - not through the desktop)
Is your computer a laptop or a desktop machine? Can you try to use a different network?
I can access the link on both my desktop and Windows 8.1 IE. I am on a laptop. I have already tried to use a different network,
Heya @VlentfulGaming and welcome to the forums!
Here are some diagnostic tips;
Please reinstall the app via the windows store
Choose “yes” to allow the app to access the internet in the store options
menu. 
Critical
Please make sure you are signed into the account that you used to
purchase the game with. Critical
Please check that you have set your windows store location to show
all aps and not just localised apps. Critical
Let us know if that helps!
Ok, since I already tried to reinstall the app, I double checked the internet option and it was enabled. I signed into a different Microsoft account and tried to install the game but it said I had to buy it and then I signed into my main account where I bought the game and I could install it and I did so I know I am on the right account. Now, the last option, I am not sure how you set the windows store location. How do I? I know this is a nooby question but is it in the windows store options or system settings? Anyway, I tried the first two and still, I got nothing… thanks for trying to help though. And, do I have to be logged into the same Steam account that I bought the game with for Windows Store for it to work?
Please help! Anyone! I mean, I have a credit card number, the Microsoft receipt, my password and e-mail to my Microsoft account. What else do you need JUST to send me a Steam key! And why did you 2 both randomly stop posting? Do I need to record the error and post it so you can see it? If so, I will try but just respond. Don;t randomly stop responding. That is not cool and also, PatrickKlug, you are a developer so don’t randomly stop responding. It may work on “test” machines but it does not work on mine. And also, if this would help, I have a Gateway made machine. (Don’t take this message on the offensive side. Just know that when it says “Get Steam Key”, I would like a Steam Key) And again, what else could I possibly do to make this retarded error go away?
I’m sorry but can you clarify what you mean with this?
My manufacturer of my laptop machine is Gateway. So the company the made my machine is Gateway.
@PatrickKlug - Gateway computers http://en.wikipedia.org/wiki/Gateway,_Inc.
An American company that was popular in the UK in the mid 90s as a low cost alternative to companies such as Dell and HP.
Most noted feature was the black and white cow design which seemed to make the product more consumer friendly.

The “Could not verify app receipt from windows store” as seen in the image below is most often fixed by;

To Disable localization in Windows 8 so you can see all Apps available to you, please follow these simple steps:
As you have reinstalled the app and confirmed that your credentials are accurate i am leaning towards thinking that this is a internet connectivity issue. Can you please list any and all security software you use such as antivirus, firewall, anti malware etc, you said your firewall was disabled but we still need to know which firewall it is as many security programs don’t fully stop functioning when disabled.
Also it is important to test the steam key functionality on safe networks. Schools, hospitals and government buildings will offer restricted access on their networks so please test on a safe and open network.
Please note that all troubleshooting & diagnostic measures are performed at your own risk.
Also you do not need to link your Steam account with your Greenheart games account. Once the webpage loads you will receive a unique numerical steam key which you enter into your steam client;
Launch the Steam client software and log into your Steam account.
Click the Games Menu.
Choose Activate a Product on Steam…
Follow the onscreen instructions to complete the process.
That I KNOW of, I have Windows Defender and Windows Firewall. I have disabled BOTH of them. I also just went to my internet settings and disabled “Pop-Up blocker” and made the internet security VERY low. I am connected to my internet by an Ethernet cable. I did everything you showed and STILL, it will not work. And where it says “undefined” for the screenshot that you uploaded, mine says “Gateway Time-out” so I do not know if that has to do with My “Default Gateway” address or my Gateway machine. Also, I just did a internet test on speedtest.net and my download speed was 32.43 mbps and my upload speed was 3.34 mbps. So I think my internet SPEED is good, but I will search for anything that will block a pop up or whatever but let me know how to do a full system check on anti-virus software IF you know how. Again, I think all I have is Windows Defender and Windows Firewall because I just reinstalled Windows about a week ago and I haven’t installed that many things. I know I haven’t installed anti-virus stuff myself but somehting may have been self attached. Anyway, I hope this helps you more and if there is anything else I could try, PLEASE let me know. Or let me if I am screwed and need to buy the game again. Anyway, thank you for your time! Oh, and one more thing. I know I am signed into the right Microsoft Store account because I tried signing in to a different account and installing the game and it said that I had to buy it. Then I signed BACK into the previous account and it said that I have purchased the game so I can install it.
EDIT: Is there a port that I could/would have to follow to make this work? Like in the port forward settings for my router setting. If so, let me know!
I FINALLY GOT THE PAGE TO SHOW!!! I changed my default browser to the Windows 8 Internet Explorer and it opened without a problem but now, I have another problem. The page is blank. Like it says Game Dev Tycoon and the top: here is the page it takes me too but the body of the website is blank white for me. Please help if you could. EDIT: I took the link off because it could have given everyone a free Steam key but when I clicked it in desktop Google Chrome, IT WORKED!!! I AM GOING TO TRY TO ENTER IT IN STEAM! YESSSSSSS!!! AHHHHHH! Sorry… I may have over exaggerated but it has been SO annoying…especially for such an EASY fix. Thank all of you for the help. If a problem occurs, I will let you guys know!
Glad to hear it worked but I’m really not sure what the issue was. @VlentfulGaming Can you outline in a numbered list what the necessary steps were to solve this?
Hopefully this can help someone else in the future.
Yes, I can.
Thanks for the feedback about your diagnostic steps @VlentfulGaming and glad you got it sorted! Enjoy the mods!
