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"

Unknown exception - code 00000001 (first/second chance not available)

Hi everyone, I am having a big issue with a fresh install of UE 4.8.2 and can not work on my projects as this is pretty bad. Everytime that I start up a project I get really pad lag/stutter in the editor, keep in mind Iv'e never had a problem since UE 4.5. When I exit out of the editor this error gets thrown.

PC Specs are as follows:

AMD FX 9370 Eight Core 5.0ghz EVGA GTX 970 4GB 24 Gb Ripjaw Ram Win 8.1 Pro 64bit

I have been using 4.82 for the past 2-3 weeks without issue on Windows 10 but went back to 8.1 Pro and running into this issue. Fresh install of Win 8.1 pro and Unreal Engine was applied.

Went back to Windows 10 and now don't have any problems with this error. Weird!
