Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

"Failed to generate code project..." 64bit Tools

Hello, Can anyone please help me? I have this code generating problem. In the logs I get the following error message!

 UnrealBuildTool Exception: ERROR: NOTE: Please ensure that 64bit Tools are installed with DevStudio - there is usually an option to install these during install

I unistalled everything, then reinstall in order: windows sdk 8.1 - vs2013 - UE4.4

Same problem appears.

What can i do with that? Thx

What I Use:

Windows 8 | Visual Studio 2013 Professional | Windows SDK 8.1 | UnrealEngine 4.4

This is likely a regression caused in 4.4.2. I have posted most details about it here:


Please report back if the suggested workaround solves the problem, and sorry again for the trouble.

Yes, the enviroment variable solved the problem!

As a workaround, could you try adding the following environment variables to your system and rerunning UE4:

FrameworkDir=xyz FrameworkVersion=1

It shouldn't matter what these are, as long as they contain some value.

thank you!
