Not Working

So, It once was working fine just fine. But then one day I tired using Infinity. When it finished after the little face. It pops up a message that says. “Installation Has Failed.” "There was an error while installing the application. Check the setup log for more information and contact the author. I checked the log and there was nothing wrong about it. I tried uninstalling and reinstalling, It didn’t work. Now keep in mind that it was working fine like 3 days ago. Now it gives me that message, If there is a way to fix this please tell me! Thank you,

Why would you uninstall it then. Anyway could be your antivirus is interfering.

What does the log say

Upload the log. You might say it says nothing is wrong.
We might say different

That link only works for you (the uploader), you need to post the public link.
