How to fix your Studio installation / Licensing issues

If you encounter an issue with your Studio installation and or licensing issues, please follow the below procedure to re-install the most recent stable version of Studio.

  1. Before you start, you might want to backup your settings.
    Please follow this guide on how to do it:
    Studio Community Edition - how to properly backup your settings

  2. Install all latest Windows Updates.

  3. Uninstall Studio from Apps & Features menu:

  4. Navigate to these folders and make sure to delete any leftover files

    rmdir /s /q "C:\Program Files (x86)\UiPath"
    rmdir /s /q "C:\Program Files (x86)\UiPath Platform"
    rmdir /s /q "C:\Program Files\UiPath"
    rmdir /s /q "C:\Program Files\UiPath Platform"
    rmdir /s /q C:\ProgramData\UiPath
    rmdir /s /q %APPDATA%\UiPath
    rmdir /s /q %APPDATA%\NuGet
    rmdir /s /q %LOCALAPPDATA%\Temp\nuget
    rmdir /s /q %LOCALAPPDATA%\Temp\NuGetScratch
    rmdir /s /q %LOCALAPPDATA%\NuGet
    rmdir /s /q %LOCALAPPDATA%\UiPath
    rmdir /s /q %APPDATA%\Roaming\UiPath
    rmdir /s /q %USERPROFILE%\.nuget
  5. Get your latest Stable Studio Community Edition .exe installer from our Automation Cloud resources:

  6. After installation, you get a few choices to license your Studio. The most foolproof method is to connect your Robot to Orchestrator. For that, see here and here.
    Another method is to simply activate your license locally without Orchestrator.

This should fix your issues with the corrupted Studio installation, including any licensing issues.

Feel free to also refer to this topic in case your Studio auto-updates and stops working correctly:

(the fix for that is typically a simple computer restart)

I solved the licensing issue just deleting “LicenseInternal” and “License” folders without uninstalling Studio.

After starting Studio again the folders where re-created and I just needed to activate the community license. That way there’s no need for backups and new installations.


I solved the licence issue by downloading the new version 2019.6 in


I was helped by this post and solved the issue. :smiley::v:

Thank you @loginerror


Is there any update on this? Still we are facing issues

I am using a licensed version of UiPath studio. But Iam not able to RUN my developed bot. the studio is getting stuck and freezes, even Message Box activity Iam not able to execute.
When i checked in the Help option, my device Id was showing blank.
Is there any solution for this kind of problems?
Thanks In advance

Hi @shrunga15

This is most likely due to a corrupted installation (probably due to Studio being closed while autoupdating in the background).

Fresh installation should fix your issue. Please install the latest 2019.10.0 Stable release :slight_smile:
