Honkai Star Rail

Honkai: Star Rail is up for pre-installation and is the latest title from miHoYo, the developer of Genshin Impact. This turn-based action title has its original characters, art style, and futuristic world. The launcher, sadly, can run into issues that aren’t too different from Genshin Impact. If you are running into the Honkai Star Rail Failed To Unzip Error, here are a few recommendations to address that.


Make Sure You Have Enough Free Space

Honkai Star Retail currently needs around 12 GB to install, so I recommend that you have at least 30-35 GB of free space in the directory you are installing it. This will ensure that there is enough space around when the launcher downloads the required zip files and then extracts those.


Use the Launcher Executable

If you’re getting an error informing you about the inability to find the “7z.exe“, head over to Honkai Star Rail’s installation location and double-click on the Launcher.exe.


Add an Exception to Your Anti-Virus Software

Anti-virus software may have flagged Honkai Star Rail as a potential threat. This isn’t uncommon in games; you can test this by adding the game to the list of exclusions or exceptions.

We have listed some popular ones and their respective FAQ pages.


Update the Launcher

Make sure that the Honkai Star Rail launcher is on the latest version. To do this, follow the steps below.

  • Double-click on the Honkai Star Rail shortcut on your desktop

  • Hello, I want to download Honkai Star rail on a zip file rather in the launcher just like you did in Genshin Impact.

  • Thank you for the guide! ^_^ I have followed your step on excluding the game from Windows antivirus, opening the launcher as administrator, and making sure that the game launcher is in its latest version. But still, my verifying steps kept on failing for multiple times (Game files verification error, it said (-3007) at the bottom corner). My net is stable, around 1.5 – 2MB/s. I have no clue on how to solve this issues ><

    • Hey! Not a problem. Can you try installing it on a different drive, maybe? Also, during the download, please ensure you don’t close the launcher without pausing it. Also, maybe don’t launch a game from the same drive while this is installed. Usually you will just need to retry a few times for this error, while making sure nothing else is going on.
