Why can't I build the source code?

VS120COMNTOOLS is set to C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\

I find out that I have VS110COMNTOOLS too should I keep it or delete it?

VS110COMNTOOLS is for Visual Studio 2012. I do not believe it will hurt anything to leave it there, but it also shouldn’t hurt to delete it.

What is the current output that you are receiving when you try to build the Engine?

I tried your solution and it finally worked out!!! :smiley: I had some special characters in the value of TEMP and TMP.

And BIG thank you to you for all the effort you spend for me!! :slight_smile: It is really appreciated :slight_smile:

Ah, so these two issues were related after all. I thought the issue that was experiencing was something completely different, and had not considered trying that solution for this issue. We all learned something new today.

I am glad that you were able to get everything working.
