Installing package



@ovi @badita @aksh1yadav I have implemented a workflow in production. Each time when I execute the process on the bot, it takes some time to install the package even if there are no changes in workflow. Why is it installing each time, if it has been already deployed in that bot. Is there any way to avoid that step and directly start job processing.



Do you execute it from Robot tray or Orchestrator?

Did you publish it locally or in Orchestrator?

Also, if it’s published and ran from Orchestrator, I’m not sure I understand what do you mean by installing the package before running the job. Can you please give more details? And Orchestrator version.


I tried both options tray and Orchestrator. It is taking some time to install the package before starting the job. I use UiPath Studio 2018.2.3 Enterprise, not sure where to check version of Orchestrator. Eg. When I start the job PROC1_PRODUCTION which already executed for many times. Please see the Info

  • Process: PROC1
  • Environment: Production
  • Robot: User2
  • Info: “Installing package…”
  • Start Time: 2018/08/29 9:29:59
  • End Time:

It took around 3 minutes to start the job

  • Process: PROC1
  • Environment: Production
  • Robot: User2
  • Info: “Job started processing”
  • Start Time: 2018/08/29 9:29:59
  • End Time:



i got the same Problem. Is there allready a fix to this Issue?




@Anthony what Studio, Robot version? Does the problem persist?


I I have the same problem I’m using version 2018.4.1
also acitivites don’t seem to be installed on robot… When I execute process it even can’t open a browser
Cannot create unknown type ‘{}OpenBrowser’


I checked %LocalAppData%\UiPath\Activities folder does not exist . I think it may be the cause of the problem


Hi @ygulas

Could you zip your project and share it with us?


Hi Maciej

I found a solution and found the root cause. After disabling and robot was able to download the activities from orchestrator. Maybe it would be nice to put a note on robot package installation that if robot does not have connection to internet before publishing and should be unchecked at development studio

Regards ,


Cannot create unknown type '{
Exception in Orchestrator

Where did you disable ?


Studio -> Manage Packages -> Settings


@ovi UiPath Studio 2018.2.3 Enterprise and same for Orchestrator. I will test the solution from ygulas and share my result later.


In my Studio Version( 2018.2.3) is no menu item for Settings. Pic related.

Is there another way to disable it? Maybe a settings file?


Hi @Anthony

I guess in this case you should see here for the guide for the 2018.2 version:
