geez guys… there is NO WORKAROUND for this error, since the only thing it makes you unable to do is update/download, everything you already downloaded (mostly) will work if you click ok/run it directly. It’s all fine and all for those that ALREADY HAVE the engine, but sucks for anyone else. Clicking ok/ running it directly is no workaround since it doesen’t solve the problem of updating things/downloading which is the only problem this error produce…
No well, there is a workaround if you want the engine badly, as in go to gitHub and compile source code from there to build your own copy of the engine. Still doesen’t let you use launcher though.
