How to Fix Unity Web Player not working issue

Unity has changed the 3D game development world with revolutionary ideas. In the earlier 2010 era, browser games all used to run on the Unity Web Players engine. But, in early 2017, Unity stopped support for the Unity Web Player, rendering all these gamers hopeless. But, what if we say that you can still play those games on your browser? Yes. It is quite possible to play the games built to run on Unity Web Player Engine.

NOTE before you proceed

As we have earlier mentioned, Unity has moved on from Web Player and stopped the support for the Unity Web Player. This was due to the mainstream browsers killing the NPAPI API support on their browsers. All the current web browser games run on WebGL.

You can download the Unity Web Player from third-party links, as the official site has removed the link of the last build.

These are ways to play the games on Unity Web Player and try this one by one. But, be prepared for glitches and occasional bugs.

 

How to INSTALL the Unity Web Player

You can download and install Unity Web Player following these steps –

1. Download the last build of Unity Web Player from here.

Carefully navigate through the steps and complete the installation process.

Once you have installed the Firefox ESR, try to launch the old browser-based game.

This should help you resolve the problem.

 

Fix 2 – Look for the latest version of the game

There is another thing you do. All the recent games have been ported to WebGL, as we have mentioned earlier. So, you can just look for the most recent version of the game on the web. Usually, web browser-based games are free and you should be able to find a newer version (or almost the same) of the old game that you are trying to play.

 

Fix 3 – Use IE 11

[FOR WINDOWS 7 users only]

If you are a Windows 7 user, there is a way you can still access Unity Web Player-based files. You can use Internet Explorer 11 to access Unity Web Player.

Step 1 – Download and install Unity Web Media Player

You can’t download Unity WMP from the official Unity website.
