Error Code R-1638

I’m trying to get 4.10 running on my machine using just the Launcher. But I keep getting and error saying Installation Failed and the Error Code R-1638.

My Windows 10 is up to date and I have tried Uninstalling the VS2015 Redist as suggested on other threads. But I keep getting the same error over and over again.

Hi Abbeysaurus,

We haven’t heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you’re still experiencing this issue, please try the suggestion that I mentioned above then post back here with the requested info.

Did you manage to resolve this? I’m having the same issue on Windows 10.

Hi, Sorry about the delayed response… I managed to get it working by simply re-downloading the whole installer.
