Lighting not building. Swarm seems to be the cause

anonymous_user_a723da02 · March 19, 2015, 10:09pm

Hi there. I am having trouble building my lighting in 4.7.3. It simply will not build at all. I get a Starting up Swarm Connection dialogue box for a split second followed by nothing.

So far I have attempted:

Uninstalling and reinstalling twice
Making sure that firewalls are allowing swarm to load
Disabling firewalls completely and then trying a light build
Testing a light build in 4.6.1 (which works)
Testing build 4.7.3 on my work computer (which also works)

This is what I get in the log for Swarm Agent

21:06:49: Starting up SwarmAgent …
21:06:49: … registering SwarmAgent with remoting service
21:06:49: … registering SwarmAgent network channels

21:06:53: … initialization successful, SwarmAgent now running
21:06:58: [Interface:TryOpenConnection] Local connection established
21:06:58: [Interface:OpenJob] Error: Invalid namespace

Any ideas on what is wrong here?

Thanks for reading

Hi ,

the “Invalid namespace” looks like Windows WMI error.

Are you using sources or binary version of the engine?
Are you able to startup SwarmAgent.exe normally? Not through the editor?

Thanks,

anonymous_user_a723da02 · March 23, 2015, 10:33pm

Hi , apologies for the late reply.

I am able to open SwarmAgent.exe.

How would I go about finding out if I’m using a binary version or sources?

Thanks for getting back to me,

Jarek_1 · March 24, 2015, 7:04am

If you downloaded the engine through the Launcher you are using a binary one.

If you synced the engine sources through GitHub and built it you are using sources.

If you start SwarmAgent.exe normally (not from the editor) what is the log in there?

anonymous_user_a723da02 · March 24, 2015, 10:48pm

I downloaded it through the launcher so that’ll make it binary.

This is what I got from the log from swarm.exe without launching the editor

Also this is what I get when I try and build lighting:

22:49:26: [Interface:TryOpenConnection] Local connection established
22:49:26: [Interface:OpenJob] Error: Invalid namespace

Jarek_1 · March 25, 2015, 7:43am

Ok, so I’d like to ask you to try something:

Close all SwarmAgent.exe/SwarmCoordinator.exe instances.
Backup SwarmInterface.dll and SwarmInterface.pdb (if it exists) in your Engine\Binaries\DotNET.
Extract contents of attached file to Engine\Binaries\DotNET.
Open up SwarmAgent.exe.
Try to build lighting again.
Copy log from SwarmAgent.exe and paste it here.

This will help me investigate as it is not happening here :(.

Thanks,

anonymous_user_a723da02 · March 26, 2015, 1:18am

Hi , I followed your steps.

When I extracted the files you sent me into Engine/Binaries/DotNET I noticed that SwarmInterface.pdb was missing.

This is the log I got from Swarm after a light build.

Hey,

that may help!

Could you verify WMI permissions for your account that SwarmAgent is running?

Here is a tutorial how to set it:

Required namespace is: Root/CIMV2.

I think minimum required permission is “Enable Account”, but if that won’t help you can experiment with full permissions.

Let me know if that helps.

Thanks,

anonymous_user_a723da02 · March 26, 2015, 8:21pm

There doesn’t seem to be a CIMV2 inside the Root folder

Jarek_1 · March 27, 2015, 9:58am

Hmm, so that’s basically our problem, cause Swarm is using it :(.

This is OS specific, but I’ll try to look around what it means and if there are some workarounds.

Thanks,

Jarek_1 · March 27, 2015, 11:43am

This page contains steps how to fix missing WMI namespaces:

You’re interested in Scenario 1, and missing namespace is CimV2.

Please, let me know if that helped!

Thanks,

anonymous_user_a723da02 · March 30, 2015, 12:05pm

I’m probably missing something simple here but I only got this far this morning. In the command prompt it says CimWin32.mof not found. These files do exist though in C:\Windows\System32\wbem

Thanks,

Jarek_1 · March 31, 2015, 9:13am

TBH it’s a OS problem and I’m not really sure how to fix it.

Could you try suggestions on this page? It seems like it solves similar problem.

Thanks,

Jarek_1 · April 7, 2015, 10:42am

Hi ,

have you managed to fix your problem? It would be helpful if you could confirm what helped in your case if anyone else encounters it.

Thanks,

anonymous_user_a723da02 · April 7, 2015, 8:13pm

Hey there sorry for the late reply. I tried the suggestions but no success.

This is what happened with the script

And this is what happened with the second suggestion.

when running winmgmt.exe/standalonehost it says please stop and restart Winmgmt. I couldn’t find it, That’s as far as I could get with it as my understanding of these sort of things are practically non-existant.

Thanks,

Jarek_1 · April 8, 2015, 8:37am

According to the forums CimV2 should be there on a healthy system. I’m affraid that we’re going to end up on some MS forums to resolve this.

Anyway, could you try one more thing? I just realized that when you said that mofcomp.exe had reported that CimWin32.mof had been missing you had executed it from C:\Windows\system32.

Could you try it again from C:\Windows\system32\wbem?

Thanks,

anonymous_user_a723da02 · April 8, 2015, 8:37pm

This is what I get when mofcomp.exe is executed from C:\Windows\system32\wbem

Jarek_1 · April 9, 2015, 8:45am

Definitely we’re getting closer, cause on my machine it finishes with success.

Are you doing it on console with elevated privledges (i.e. as administrator)? If not, please retry as admin.
