Sorry I’m confused by the title, when you say without Source control do you mean this will work without downloading the Source from Git?

Works great with binaries on 4.12, thanks so much! I’m going to try applying it to 4.11

I can confirm these exact instructions also work for 4.11.2, thanks again Rigjaw!

any ETA on a proper fix for this ?

You are my Hero, This worked beautifully. Thanks a Million!

Thanks very much for posting this, Rigjaw!

I can confirm it works on the 4.12.4 version. Thanks Rigjaw! but if I may ask, what does this do exactly?

this didn’t fix ****.

Read the Error Message?

When Visual Studio is Installed you must Install C++ in Visual Studio to it doestn install it in the default Settings.

When you Uninstall Visual Studio you can choose in the Uninstall Window “Modify” and under the Programming Languages Section Activate Visual C++ and then press Update.

You can also download Visual Studio 2015 Update 2 here:
