Hi @Zoeyu ,

following steps:

  1. Open your project in UiPath Studio.
  2. Click on the “Project” tab in the ribbon.
  3. Click on the “Manage Packages” button.
  4. In the “Manage Packages” window, click on the “All Packages” tab.
  5. In the search bar, type “System.ComponentModel.TypeConverter”.
  6. If the package is already installed, make sure it is the correct version. If not, update it to the correct version.
  7. If the package is not installed, click on the “Install” button to install it.
  8. Once the package is installed, try running your workflow again.



Hi @Zoeyu Did you get this update after upgrading studio or Ui Automations package

If it exists after upgrading UiAutomations package, then you can you try degrading that package and check (please back up your existing project and try this)

Im having the same issue. I tried manually installing the System.ComponentModel.TypeConverter package but I get “Package Installation Failure”. I didn’t even upgrade any of the other packages I use. Everything just broke in every single process I have. This is serious.

Getting the same error. When I try to install the package System.ComponentMOdel.typeConverter version 4.3.0 it says the package is emtpy.

Thanks a lot

Restart and it repair itself
