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"

Packaging Results: Error Unknown Cook Failure 4.10(Please Help)

Hello Guys,

I tried to package the current version of my game for Windows 64bit, but as some of you experienced before I recieved a Cook Error. I am using UE 4.10. I read most of the topics regarding this error some of them gave solutions some of them were uncomplete. But none of the solutions I read worked for me :/

I tried:

  • Upgrade to version 4.11 and try to package the game;

  • Rename the folder whre the project is, Open it again, Close it, Rename the folder to its original name, Open it again and package it;

  • Delete the three folders in my game folder(Config,Saved and Intermediate) and then package the game.

  • restart my computer, open the project, refresh some of the blueprints(using refresh all nodes command) and package the game.

  • Re-save all of my materials and package the game.

  • etc, the list is long.

I read that I need to upload my error log so you guys can have a look yourselves: https://www.dropbox.com/s/lakel0pfs5lnsna/Packedge%202.txt?dl=0

I hope that you can find the missing peace of the puzzle that I did not.

With kind regards,

Todor Tsekov.

Hi Todor,

a few of other things to try

Fix redirectors (right click Contents, Fix Redirectors...)

Disable most plugins you don't use, especially the experimental ones. This works 80% of the time.

Try package before cook

Hope it helps, let us know what worked if it worked.

Hello Keyle,

First of all thank you for the fast response.

I did the first step which is Fix redirectors.

I am not sure how to do the second step, I mean from where can I disable all the plugins? I searched in the project settings and I found a Plugins section but there only 3 plugins sort of speak to choose from. Is that it ? And I have a problem I am using experimental plugins :/ Like widgets attached to pawns and actors( I hope I explaind taht well).

For the third step- how can I package before cooking. I looked in the project settings again under packaging but I could not find it. Any suggestions?

P.S. I tryed to package the game with one the first step done ofcourse :D but it didn not work out.

For the second step I mean the Widget Component which is experimental class.

Todor, from the menu, Edit -> Plugins - turn off most things you don't need and restart UE4.

yeah Package before Cook I meant File -> Package project, then try Cook after.

Let me know :)

Hello Keyle,

I had some testing to do today, so I couldn't answer right away. I followed your steps, but it didn't work out :/ Now when I press edit i cant see the pluging option anymore. I saved my package report and my cook report after packaging. If you think they might help I can upload them as well.

Do you know of some other way that I can try out?

Thank you for the help.

Hello Guys I solve my error by following this post : https://answers.unrealengine.com/questions/391694/runuatbat-error-7.html Now I can package my games with ease :) But after that I had another error where I can't run the packaged .exe but I found a solution for that also : https://answers.unrealengine.com/questions/262680/failed-to-open-descriptor-file-error.html Read this article. The solution for me was : schubboy Aug 27 '15 at 4:59 PM

Somebody else suggested going into the /bin directory and change the exe name to not include '-win32-shipping' - EG: make sure its the actual name of your project. That worked perfectly for me.

I hope I helped you guys. :)
