Dear community, has anyone succeeded in setting up UQLab on a Linux Cluster with Matlab running on the **-nodesktop** Option? Any ideas for workarounds? Best, Robert ---

Dear Robert, It should be possible to run UQLab on a cluster. Can you please share your error message? Best regards, Styfen ---

I’m starting Matlab on the Cluster (matlab -nodesktop) and proceed as described on the download page. I receive the following warnings ![grafik](https://uqworld.org/uploads/default/original/1X/73fcd127e448fd27b585859b10a940c1420f472f.png) Right now there is no possibility to run an interactive desktop session on the cluster. From past experiences installing UQlab on Matlab and the need to start Matlab without the -nojvm option to install UQlab I guess that I cannot pass a window that pops and needs input somewhere. Is there a workaround? I think this might be relevant also to others. ---

Hello @Robert, The dialog that tries to pop up is probably related to the uq\_license.p file not found inside the core folder. In that case, such a dialog window pops up, asking you to point out the location of this file. Normally, when not running in desktop mode, a message should be printed instead, letting you know about this issue. We are looking into why the installer did not properly figure out that you are running in a non-interactive mode. In the meantime, could you check whether the error is resolved simply by copying your license file inside the core folder? ---

Thanks for your reply. The license file is already in the core folder. Might it be a problem that it is the same license file that I used to install UQlab on my personal client PC? ---

Using the same license file in your PC should not cause any problem. Here is another straightforward way to resolve this issue: you can directly copy the UQLab installation that is running on your PC to the cluster. That way you can bypass the installation step. ---

Hi @Robert, I would like to follow up on the reply from @c.lataniotis. To bypass the installation step, you can download manually the modules with the following steps: 1. Make sure that you have downloaded the “core” and put your “uq\_license.p” inside 2. Download manually all the modules from the [link](https://uqftp.ethz.ch/uqlab_releases/download_modules.html) and then unzip them 3. Move all the modules inside the unzipped folder (by default it is named as “UQLabModules\_Rel1.4.2”) to the same folder as the “core”, meaning that in your uqlab installation root you should have the following folders: “core”, “Doc”, “Examples”, “lib”, “modules”, “Profiles” and files: “CHANGELOG”, “CONTRIBUTORS”, “LICENSE”, “ListOfFiles” 4. Open Matlab and navigate to the “core” folder 5. Exercute “uqlab\_install” in the command line ---

Just loaded the UQLab files of my client PC’s installation on the cluster and the selftest works, thanks! ---
