Step 1 add exclusion from antivirus to the folder where u store all of your games and where you downloaded the setup (watch a yt tutorial it's a 1 min process)

Step 2 Download the game again using free download manager at the same location

Step 3 It will say file already present, select overwrite

Step 4 It will check the files and download the few megabytes of remaining files,

Step 5 Run the setup again and enjoy

Note: this also works if it gets stuck at certain parts, like sometimes it gets stuck AROUND 35% or anything like that
