Unable to Run Project in Unattended Mode

[sameer73]

Hi All,

I am unable to run automation in unattended mode after the recent update. The machine I used for development and the machine configured for unattended mode are using the latest version of UiPath. The project runs perfectly in Attended mode in both the machines, but fails in unattended mode.

I tried Uninstalling and Installing, clearing cache, erasing UiPath related files from .nuget . But did not work.

Please help me fix this issue.

HI @sameer73

Checkout this thread

Unattended but working only when the screen is open

Thanks a lot @seanrockvz13 for explaining to me about many things. After checking the whole system setting again . I have come to know that the path is installed with the Robot type as User Mode in the non-working VM . After the reinstallation is done with the robot type as Service Mode the VM is working fine. [image] If anyone faces the same issue you need to check this first in task manager->Details [image] There should be a Service. host available in the running state for unattended and…

Hi @Sudharsan_Ka ,

Thanks for your response. I would like to add that the unattended mode worked until the recent update.
It still works for the projects which were developed before the 2023.2 update. Only the projects developed in the latest version of the UiPath Studio seem to be failing.

Thanks.

I am having the same problem but with attended mode. After updating I can run my RPA using Studio but getting the error below when using Assistant 2023.2.0

Could not load file or assembly ‘UiPath.CodedWorkflows, Version=23.2.0.0, Culture=neutral, PublicKeyToken=null’. Den angivne fil blev ikke fundet.

@sameer73 please try to upgrade systems.activities package

[irahmat (Indra Rahmat)]

are you connecting with company network?

[sameer73]

It is already upgraded @raja.arslankhan .

[sameer73]

No, @irahmat . I am not.

[raven]

already upgraded - it happened after upgrading

[raven]

No I am not, community edition

[raven]

I solved my problem installing latest dependencies packages: Microsoft.CodeAnalysis.Common and Microsoft.CodeAnalysis.CSharp.Scripting

[sameer73]

Thank you. This did not work for me. It worked when I just downgraded the packages to 22.10 stable version.

[raven]

I was not able to downgrade because I am using community edition where I am forced to use beta versions of Studio – if this practice is not to be discontinued it does not make sense for me to keep using Studio because lately I am spending all my time finding errors due to beta versions that are being automatically installed. In this way I am never going to have a stable version of Studio.

Happy to hear that you found a solution

[nuno.lucio]

Using Studio…downgraded system package to 22.10.4 and error is gone

EDIT - From Orchestrator, only 22.10.1 works…

[kcelik.istanbul (Kcelik)]

“downgraded system package to 22.10.4”

[irahmat (Indra Rahmat)]

yes, you can downgrade the dependencies version. just click manage package.

the community always forces you to use the preview version. but you can use the stable version of your dependencies. you just need to have little bit aware everytime you create a new project, you need to downgrade to stabil dependencies.

[raven]

No I was not able to downgrade the dependencies to a lower version. Got an error.

Community version was able to select whether you wanted stable or beta version. Now since lately this choice has been eliminated, which is extremely annoying because I am experiencing all kind of errors and bugs with no way to avoid the mess. Being forced upgrading to beta versions all the time and never have a stable version will make me stop using Studio in the future.

[irahmat (Indra Rahmat)]

do you mean this dependencies cannot being downgraded

don’t you?

[raven]

The 23. versions cannot be downgraded without errors.

Regarding Studio, again it has been upgraded to a new beta version and again I am having errors when opening my RPA. Getting CRAZY with these forced updates that are destroying my RPA.

[irahmat (Indra Rahmat)]

I am not sure what is wrong with your studio CE. but we did try downgrading here without any errors.
