Composer won't launch

Hi, composer will no longer launch for me, after clicking launch, it gets the spinning icon for a couple of seconds then it goes back to the launch button and nothing opens. I’ve tried different versions and reinstalling and neither fixed it.

If I run the omni.create.bat file I get an error saying carb.dll was not found but it is present in the kit folder.

Logs attached. Anyone know of a fix? Thanks!

Try uninstalling and reinstalling one more time, but this time make sure you delete everything in the ov folder AFTER you have uninstalled everything from Launcher. So cache, data, etc.

I am having the same issue. I’ve uninstalled and reinstalled a few times. I’ve also reset my windows settings and still nothing.

Thanks Richard, that fixed it!

Same for you @metarick88 Make sure you uninstall all your ov apps and then make sure there is nothing left in the OV folder at all. Before you flush out the folder, you will need to fully quit launcher and kill any threads starting with “omni” in the task manager. Then go ahead and totally flush out the ov folder.

Thank you for your response. I’m now receiving the following import error :

100% user error. I’m not sure what dependency I deleted from my system, but I restored my windows system. Omniverse now loads correctly when I launch.

Great thanks !
