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"

4.6.1 Failing to Launch

I have re-installed, deleted all known folders in ProgramData and AppData/Local, and I still cannot launch 4.6.1. There was an issue with the older launcher where if I had 4.6.1 installed, I couldn't click on Library without the launcher crashing, but deleting the Manifest for it solved that. The new launcher doesn't crash but every time I try to launch the engine (with or without a project) it crashes.

1 answer: sort voted first

Figured out the solution finally, there's old stuff left by the previous launcher that was in the folders %userprofile%/AppData/Local and C:\ProgramData. After deleting every Unreal related folder, then uninstalling/reinstalling the launcher and engine, everything is working again.
