Unity Web Player Troubleshooting

• Windows Vista or later; Mac OS X 10.5 or later
• Chrome, Edge, Firefox, Safari, Internet Explorer 10+ (Unity3D Web Player)

1. Download the installation file found here: http://unity3d.com/webplayer
2. Select 'Run' to begin the installation process, or save the file and double-click the downloaded file.
3. You might have to close the browser and open it again after installing Unity Web Player.

1. Close all browsers.
2. Use Control Panel to uninstall the Unity Web Player.
3. Reboot your machine.
4. Download a new copy of the latest webplayer plugin from: http://unity3d.com/webplayer
5. Again close all browsers.
6. Run the webplayer installer.

If Unity is not loading or is encountering errors then we need to try some of these steps...

1. Refresh the page.
2. Try another browser... Chrome, Firefox, Safari, etc.
3. Check Unity Web Player for updates and make sure you have the latest version installed from the official website.
4. Check if your firewall has blocked Unity Web Player. If so, add it to safe list or unblock it.
5. If the problem persists, uninstall and re-install Unity Web Player from your computer, close all browsers.
6. If it still doesn't work, even though most problems stop at this stage, reboot your system.
7. Do you use Avast Anti-Virus? Then add Unity Web Player to your Exception List.
8. Perform a System Restore. There might be some undetected problems preventing Unity Web Player from functioning. If a system restore and all above solutions do not seem to work, this is a problem with your system, modem, or Internet Connection.

1. Try installing the Unity Web Player from here: http://unity3d.com/webplayer. Save the installer to your desktop, right-click it and choose 'Run as administrator'.
2. See if the unity info files have a version mismatch. See the first reply in this thread..
3. The Web Player uses this temporary folder, clearing it might help... C:\Users\{username}\AppData\Local\Temp\UnityWebPlayer.
4. Download manager programs such as Internet Download Manager, can cause problems. If you are using one, disable it.
5. Programs that encrypt files on your hard drive can cause problems. If you are using one, disable it on the web player folder.
6. Unity Web Player is installed here on Windows 7... C:\Users\{username}\AppData\LocalLow\Unity\WebPlayer. Problems arise if you are not able to read or write to this folder. Some network setups might restrict user access.

1. Make sure you are using the browser's 'Print' feature (Ctrl-P or choose 'Print' from the browser’s menu), not right-clicking the image and choosing 'Print picture'.
2. Make sure you are not using an old version of Internet Explorer. Version 8+ is required.
