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"

[Closed] Packaging and Launching Unreal Project using OpenCV

Hi All,

I'm working on a project in Unreal using OpenCV. I used this tutorial in order to get it working: https://wiki.unrealengine.com/Integrating_OpenCV_Into_Unreal_Engine_4 I've since modified some of the code for my project. I'm testing on two different versions of the project as described in the wiki artcile, one using the plugin, the other custom installed. Both have the same problems.

Whatever I do, I cannot get the project to successfully launch or package for Windows64. It plays in editor fine, and it packages for Windows32 without problem, and the resulting program works as it should. The error messages haven't been too helpful.

On launching the project: PackagingResults:Error: Error Launch failed! Unknown Error

On packaging for Win64: PackagingResults:Error: Error Unknown Error

I followed along with this similar question, but still have not been able to get it working: https://answers.unrealengine.com/questions/99854/launch-failed-error.html

I've gone through all the dll's I downloaded and unblocked them. I tried to use streams, however after running the .exe I can't seem to use the "streams" command in the command prompt (the command isn't found). Does this seem like the problem?

As a potential complication, I'm using a Japanese version of Windows 7, a language which I'm not quite fluent in, and there seem to be minor differences between the systems.

Any idea how to fix this problem?

Product Version: UE 4.10
