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"

ERROR: UnrealBuildTool Exception: System.ArgumentException: There are invalid characters on the path.

I am getting this error while creating a new C++ Basic Code Project.

 An error occurred while trying to generate project files.
 Running C:/Program Files/Epic Games/UE_4.19/Engine/Binaries/DotNET/UnrealBuildTool.exe  -projectfiles -project="C:/Users/Cahit/Desktop/ATS/ATS.uproject" -game -rocket -progress

           konum: UnrealBuildTool.UnrealBuildTool.GuardedMain(String[] Arguments)

Note: "Yolda ge?ersiz karakterler var." means "There are invalid characters on the path".

But I can't see any invalid characters on the path. I also tried to create the project directly on C drive.

There was no problem with the version 4.18. I also checked the Cisual Studio installation. I have all the required Windows SDK versions.

Can you help me?

Product Version: UE 4.19
