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"

UE4 crashes at 45% on startup !!! please HELP

Hello community, I really looked for a solution to my problem but I didn’t find, please help me! When I launch UE4 version 4.17.0 from Epic Games Launcher it crashes at 45% and shows the crash reporter. I installed Visual Studio 2015, I downloaded the latest driver for my GPU, I tried to reinstall UE4 5-6 times but it still crashes at 45%. Here is the summary information:

Try to get some UE4 source code from github and compile it manually (there is an instruction for it).
