As I mentioned (I got it to package but this message keeps popping up (PackagingResults:Warning: Warning Warning Unable to find package for cooking /Game/Maps/Menu)
I can’t open the packed file.)
I was finally able to package the file thanks to you and saeedc, but I can not open the packaged file. I tried repackaging it a couple of times. I can’t think of anything else.
Hi
ProjectSettings>Maps & mode check to see if you have selected a map as default map 
and also default gamemode
This would be a good thing to check. I had to remove all of the maps you had set to package as the file paths didn’t match up with my directory, so that could be the problem. I can confirm that I’m able to open the packaged file.
I still can’t open the packaged file. What do I do?
Have you tried checking what saeedc mentioned? Inside of Project Settings > Packaging and then under the expanded options, there should be a list of maps to cook which you added entries to. Can you ensure that the /Game/Maps/Menu map isn’t listed there?
Yes I have done that.
Please try to be more descriptive in your responses. While I understand that you have tried the fix, what were the results? Is it still failing to find that map? Is there a new error? A new set of logs after trying these fixes (removing the spaces, checking the packaging settings) would be useful to help determine what is continuing to cause these issues.
I still can’t open the project after packaging it.
Here is Warning/Error Summary and I already got rid of everything to do with ThroneRoom_Surfaces but I do not know how to take care of the other errors like the SM_GibChunk because if I delete those my particle effects will be ruined.
Thanks
I have a few things for you to try and a few things I need from you for some more information if those don’t work.
First, open up the Edit > Project Settings > Maps & Modes menu and set a map of your choice for the “Game Default Map” if there isn’t one already set.
When going to open your project, please ensure that you’re attempting to open the .exe located at DemoFinale\WindowsNoEditor which matches the name of the project and not the UE4game.exe located deeper within those directories.
Try making a copy of the project and removing the assets that are causing these warnings one by one to see if, by trial and error, you can find the assets that are causing the issues. Sometimes this is the easiest way to figure out what the problem is.
If none of these help, please take screenshots of the following windows for me so that I can at least try to recreate what you’re running into.
-The Maps & Modes window, with the top settings field expanded
-The Packaging settings window (Inside of Project Settings) with the bottom settings field expanded, showing the list of maps to cook
-The error message that you get whenever you try to open the packaged project
Do you log in to your pc as administrator?
There is only one user on this pc and yes it is administrator.
After looking at the logs you provided, I noticed that your project’s directory name still has the invalid space in it. Please remove the space between “demo” and “finale” in the name of the project’s root folder. This should alleviate the access issues.
Where do I find the project directory name?
That would be the name of the folder that your project is in, so the one that is currently called “demo finale” on your Desktop.
Changed the folder name still having problems.
Is there any other solution to fix this entire project?
there are some warning like this one Warning: Can’t find file ‘/Game/2DSideScrollerBP/2DSideScrollerOverview’
or this 
Warning Warning Unable to generate long package name for …/…/…/…/…/…/Users/ /Desktop/demo finale/Content/Maps/Untitled.umap because FilenameToLongPackageName failed to convert ‘…/…/…/…/…/…/Users/ /Desktop/demo finale/Content/Maps/Untitled.umap’. Attempt result was ‘…/…/…/…/…/…/Users/ /Desktop/demo finale/Content/Maps/Untitled’, but the path contains illegal characters ‘.’
take a look at them. probably the location of those assets which are mentioned in those warnings have been changed or they are removed.
can you launch a level of your project directly from editor on your device?
oh I saw this right now. illegal character
Users/ /Desktop/demo finale/Content/Maps/Untitled’, but the path contains illegal characters ‘.’
you have to dig in your logs and study those warnings one by one and solve them one by one.
it is easy but needs time and patince
