Unrealbuildtool.bat fails :line 554

OS: Win-7 64bit Professional

I’ve attempted using both the github fork, and with the downloaded source and have not been able to successfully run the unrealbuildtool.bat file when following the tutorials here and here. Listed below is the command prompt message.

Setting up Unreal Engine 4 project files...

Could someone please help with this error?

I don’t think the builder liked my folder named “# Dev”. I renamed the folder to “- Dev” and it created the UE4.sln & UE4.v12.suo files.

Yes, that seems to have solved the problem. After renaming the folder, and following the answer listed here for visual studio 2013 express I was able to build the editor.
