I've seen quite a bit of people having issues with launching RuneWild.
So I will show you how you can fix it on your end, if this doesn't help you it's most likely you have malware in your computer.
Step 1: Click "Play now"

Step 2: Click "WINDOWS CLIENT" The difference between these 2 is that Java client will launch automatically and windows client downloads and makes a shortcut onto your computer. We're going to do windows client incase you're having issues launching.

Click the arrow next to "Save" and Save as.

Step 3: Once you're done with saving it in your desired location, click "Run".
You should be prompt with a thing that says "Unknown publisher or runewild.exe" click "Yes" then you'll see this.

Last click "Install".

Now you have a shortcut on your computer, and you can click finish then the game should automatically launch for you and you're set.
if it didn't launch and you downloaded everything this is what you do.
Go to your file explorer and look for this

Click "Windows (C:)"
Next you should see "Users" Click that.

Now click your username in this case for me it's Justin so click it.

Top right Search for "runewild" then click runewild folder.

Now you see the "cache", we're going to delete all of it.

Once everything is deleted click the shortcut you have and it'll run.
