‬Hi, sasakekez221,

I hope you are doing well today. Welcome to the Xbox Community. Thank you for sharing that video and providing me with what's happening with Hitman 3 on PC Game Pass. Let me provide you with some suggestions, and please try them in the order that I have numbered them. I hope this resolve your problem.

Solution 1: Use the System File Checker tool to repair missing or corrupted system files. If some Windows functions aren't working or Windows crashes, use the System File Checker to scan Windows and restore your files. Sometimes corrupted files can cause issues.

Solution 2: Reset Windows 10 store & Xbox app

1. Open Settings.

2. Go to Apps -> Apps & features.

3. Look for Microsoft Store/Xbox App and click it on the right side.

4. The advanced options link will appear. Click it

5. Next, click on the Reset button to reset Microsoft Store/Xbox App to the default setting.

Solution 3: Try reinstalling the Gaming Services package on your Windows 10 device:

1. Right-click the Start button in the lower-left corner of the main screen, and then select Windows PowerShell (Admin).
   
2. In the Administrator: Windows PowerShell screen, type the following command and press Enter:
   
3. Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers
   

Solution 4: Play games offline on Windows 10 using Offline mode; this error could also be attributed to issues with the Microsoft store not recognizing your entitlement to the game. Would you please click on this link Play games offline on Windows 10 using Offline mode | Xbox Support. Then scroll down and click on the drop-down arrow and look at the steps for How to enable offline play on your device

Solution 5: Disk cleanup in Windows

Please follow this link and perform a cleanup. You should see the 100GB or more, and you can then remove them this way.

I hope these suggestions help! If this answers your question, please mark the thread as "Answered." If this does not resolve your issue, please let me know, and we can continue to try other things to see if there is a solution.

Installation problems. I got prompted to install update. I accepted. It was stuck at 99% for a really long time. I paused the install and then canceled the install. I turned off the XBOX and retried the install. This time I got a warning that the install
was 6gb. I accepted. It has be STUCK at "0% Install" for over an hour. Not sure what to do at this point.

I launched the game although it's installation gets queud at 99%,and now I'm stuck in game, yep, it is "installing"... great feature !
