UiPath Release Notes

Release date: 10th January 2019

What’s New


This new year brings two more languages in the entire UiPath Platform - French and Russian. Since we layed down the foundations of localization in our previous release, we are continuing our efforts in bringing you a more immersive experience and lowering the language barrier bit by bit.



Projects created in Studio v2018.3 that contain UiPath.UIAutomation.Activities dependency version higher than and lower than version 18.3.6877.28298 are automatically migrated to the latter version.


A confirmation dialog is now displayed when you grant a user Edit permissions on Machines.


To help you get a better handle on what happened during the setup process, UiPathStudio.msi now also logs licensing information (regutil.exe) while it is running, at a custom location.

Known Issues


  • Some logs are not localizable in the Output panel or the Studio log file. For the Studio log file to be localized entirely make sure the machine’s keyboard input language is set to Japanese, Russian or French.
  • Values for Boolean data type variables and arguments aren’t localizable.
  • If the Russian, Japanese, or French .Net framework language pack version is different than the .Net framework version running on the machine, Studio is unable to create or open projects. The .Net framework and related language pack version must correspond, and any additional .Net framework versions installed on the machine should be removed.

Bug Fixes


  • Running processes could not be stopped on Studio Community Edition UiPathStudio.exe with the update channel set to Stable, and UiPath.Service.Host.exe and UiPath.Agent.exe running before opening the updated Studio.
  • When the language was set to Japanese, using Web Recording did not type into fields if the Empty field check box was selected.
  • Certain Studio ribbon icons were improperly displayed when the window was resized.


  • Fixed an issue which caused the Invoke Code activity to fail at runtime when trying to load the System.IO.Compression assembly.


  • Multiple quartz triggers were generated in the database for non-existing jobs. This had a detrimental effect on the performance of the scheduling functionality.


  • When the language was set to Japanese, reporting a document as an exception in the Validation Station did not generate an error window.

Activities Versions

The following activity packages and versions are included in the installers and are added as dependencies, by default, to a newly created project in Studio:

  • UiPath.Excel.Activities - v2.5.0
  • UiPath.Mail.Activities - v1.3.0
  • UiPath.System.Activities - v18.4.2
  • UiPath.UIAutomation.Activities - v18.4.3
