for some reason when I try to install infinity I get an error where it says “failed to download please wait a second while required files downloading” please help
From which link are you trying to install ? From here, https://www.wemod.com/infinity ?
Try to disable your AntiVirus/Firewall, so that nothing blocks the download accidentally. Which OS do you have ? Use a different WEB browser.
You can try manually deleting the CACHE folder, which can be found under C:/username/Appdata/Roaming/Infinity folder.
Once you have deleted the cache, reinstall infinity once again. Try the BETA client as well:
