How to Fix the Roblox won’t Install Issue on Windows?

Roblox is the ultimate online universe where you can play mini-games made by users, enjoy their universes, and create your world for others to enjoy. It’s a great cross-platform idea but many users complain about Roblox not installing properly on Windows at all.

Roblox Won’t Install

Roblox installation is very simple but users claim that it often crashes midway through or it ‘finishes’ but Roblox still can’t run and it’s not recognized as installed. Either way, We have prepared several working methods for you to check and we hope you will be able to resolve your problem!

What Causes Roblox to Fail to Install on Windows?

Pinpointing many direct causes to this specific problem is difficult and most troubleshooting methods come down to performing certain workaround which causes the installation to work properly and the problem is dealt with. However, it’s possible to take note of the most common cause which should be taken care of.

The main installer executable is often prevented from running properly by the antivirus tool you have installed on your computer or directly by Windows Defender Firewall. You should consider adding the launcher as an exception in both the antivirus and the firewall before trying again. Also, providing administrator access seems to do the trick!

Solution 1: Disable Your Antivirus

Sometimes the Roblox installer has problems gaining enough permission on your computer to access certain files needed for the installation to go through. This often means that your antivirus program is blocking the tool!

Disabling the antivirus is a process which greatly differs from one antivirus tool to another but everyone should disable Windows Defender for the installation to succeed so follow the steps below to do so!

Still, most of them can be disabled by right-clicking their entry in the system tray (lower right part of your screen) and choosing the Disable option.

If you receive a message saying that some files couldn’t have been deleted because they were in use, make sure you end all Roblox-related processes in Task Manager. You can also simply move the files and folders somewhere else for safekeeping! Check to see if Roblox is now able to install properly.
