Cannot install Cache

I have installed the Omniverse launcher and from there installed Drive, Create, a bunch of connectors and even created a collaboration server on localhost… but from day one until just a few minutes ago, I simply cannot install Cache 1.5.3.

It simply fails all the time saying: Error occurred during installation of Cache. Command failed: “D:\Omniverse\Library\cache 153\setup\cache-setup.exe” -i -c “D:\Omniverse\Cache”.

Mind you, I am still very new to the Omniverse and only now starting to play around with it with an eye on making this my default workflow if it all pans out. Since I am this new it is likely that I am just doing something stupid but, for the life of me, with everything else installing just fine I have no idea what this thing’s problem is and that error message is absolutely all I have to go on.

hi @mybadstudios, sorry to hear that you are having difficulties installing Cache. Can you provide us some information such that we can help get this resolved.

  • Do you have admin rights for installation?
  • Can you share with us the installation logs?

Logs are located here: C:\Users\ “windows username” \ .nvidia-omniverse\logs

Please compress the entire folder and upload them to the discussion.


I’m trying repro your issue, but I’ve had no luck so far unfortunately. I’m using Launcher 1.0.38 and was able to install Cache 1.5.3 to my D: drive.

Do you have access to System Monitor? If you open localhost:3080 in a web browser you can use System Monitor to configure Cache settings.

Is your Launcher up to date? Latest is currently 1.0.38 and you should have gotten a notification to update if you haven’t already.

Does changing the install location for cache do anything? Install location can be changed from Settings, by changing Library to a different path. From the looks of it, you currently have it set to D:\Omniverse\Library.

Okay so this is weird… I located that logs file and had a look inside. It would be a total waste to send it to you since the entire file is just this over and over

I can’t imagine anything being out of date since I only installed everything about a week or so ago. This means I downloaded everything on the same day so it is highly unlikely that anything would be out of date. As for admin rights, it is a single user PC… the admin account is the only account on this PC so, definitely have admin rights.

Next up I went to localhost:3080 and took a screenshot of what was there (everything running under Applications, nothing installed under Cache) so I could show you and maybe you could see something was missing…

Next I tried to install Cache once again so that if it DOES make any entry in the logs then it will be at the end and easy to spot when I send you the logs.

…this time Cache installed without any problems. 🤷‍♂️ I have no explanation for it. The only thing I did differently this time was going to the Connections tab and actually STARTING my connection to localhost before I tried to download and install Cache. That sounds like it might have something to do with it… also, not really. But maybe?

In any event, it is installed now so all is well.
Just in case, I am uploading my logs anyway in the hopes it might prove useful in finding out why this happened and possibly preventing it in future installs. (647.5 KB)


The entry in the logs regarding “Checking for update” is expected. Thank you for providing logs. Glad you were able to get Cache installed. We will investigate further to see if we can pinpoint the root cause such that it does not happen in the future. In the meantime, enjoy Omniverse and let us know if you have any other questions.

Same problem happening for me.
I can’t install cache.

I keep uninstall and installing it, but it is failing.

@jinbeom7029 @kyzhao a couple of questions

  1. What Windows OS are you using. (use winver program to get this info)
  2. Did you configure the Windows OS with a language other than English? If so which language?

Windows 10, Chinese. When I change it to English, it works…

This issue should be resolved with latest version of Nucleus on the Launcher R7 Hotfix (2020.3.2)
