.NET required during installation

Observed behavior

When using the .msi installer to install or upgrade Studio and/or Robot, the installation fails with the you must install .NET Desktop Runtime to run this application error.


There are corrupted versions of .NET installed on the machine.


  1. Uninstall all .NET x64 SDKs or .NET x64 Runtimes from Add or remove programs.
  2. Delete the C:\Program Files\dotnet folder.
  3. Run the UiPath® installer again. This also adds the .NET runtime required by UiPath®.
    1. Optional: re-install the SDKs/runtimes removed earlier. UiPath® does not need an installed runtime, but other apps on your PC might need them.
