why is minecraft luancher showing that luach failed and unable to decompress file

Hi there! This is Virginia O.

I understand that you are experiencing issues launching Minecraft Launcher.

I apologize for the inconvenienced this has caused you. I will do my best to help you.

Please run the Launcher as administrator. To do this, right-click on the Minecraft Launcher shortcut and choose "Run as administrator."

And then check for antivirus or Windows defender interference because your security software can be blocking the launcher from modifying files in the specified folder. Temporarily disable your antivirus or you can also add an exception for Minecraft and its directories and then launch it again.

Next is to verify Windows file permissions. Make sure that your user account has full control of the folder mentioned in the error by right-clicking on the folder, select "Properties," go to the "Security" tab, and check that your account has the necessary permissions.

If the issue persist after performing the troubleshooting steps, uninstall and reinstall the Minecraft Launcher that will resolve corrupted installation issues.

Thank you for your cooperation.

One thing you should remember is that flight simulator will show you the status of decompression of the packages it's downloaded, so what you're likely seeing as many small files starting decompression and finishing quickly and that's why your meter keeps jumping. Please leave it alone and see if it finishes

Also PS3 actually decompresses the files and installs the games on the HDD like a PC (hence why it takes so long). X360's installation feature basically creates an disk image on the HDD, which meant the files would still have to decompressed in real-time.
So the whole bandwidth argument is completely invalid.

How do you find the files that are not decompressed?

Flight simulator needs additional space to decompress the Files it is downloading
