UiPath Studio Community Edition doesn't work

[Tim_D_haeyer]

Hi,

I installed the Community Edition of UiPath Studio this week, but I can’t run any workflows.
Also when starting the application, it takes a really long time untill I can actually do something.

This is the error I get

I already tried to reinstall studio, but it doesn’t help. Even uninstalling doesn’t work.
I’m using a windows 10 machine in a corporate domain.

Kind Regards
Tim

Hi @Tim_D_haeyer,
Welcome to the Community!
It’s hard to say what can be the problem here. As you mentioned it’s corporate machine. I think you should at first talk with your company IT, maybe they have some restriction through GPO applied.

Hi,
I have the same problem.
Only before it worked for me then after a restart of the Computer I realized before that the projects were saved only in part or not saved (after having saved them carefully).
After Uipath Studio it didn’t work anymore.

I tried to Uninstall it and then reinstall it but nothing.
How can I proceed.

Thank you,

F.

I forgot to add that for me it is also a corporate computer and I have already heard our IT.

Hi @Tim_D_haeyer

Maybe you can refer solution in below article:

I tried to kill that process already, but I can’t find it in my list.
I did check the event viewer and see following error message.

Which version of .Net Framework do you have?

[Tim_D_haeyer]

[Tim_D_haeyer]

Just a note, I have a colleague who is running an older version of UiPath studio without issues. His version is 2019.8.0

[Tim_D_haeyer]

Any update on this? I’m still unable to run any robots.

[Pablito (Pawel Wozniak)]

I’m not 100% sure but it still look for me rather like a local PC issue that something related to software. Meanwhile on platform.uipath.com there is new 2019.9.2 version available. Please try with it using this instruction:

Hi @RPAvarthini Did you have any version of Studio installed before? I would suggest you to: Uninstall Studio Clear these folders:%userprofile%\AppData\Local\UiPath %userprofile%\.nuget\packages Install Studio from the Community Installer You can download the latest version from our platform.uipath.com: [image] Make sure no firewall/antivirus is blocking the software Run Studio from Start menu and activate it. (you can also run Robot from Start menu first and connect it to our Orchesta…

[Tim_D_haeyer]

@Pablito No same result. Are there things that I can check to find out what the problem could be? If I go to our infra team to check the GPO’s they will not be able to help me without more information.

[Pablito (Pawel Wozniak)]

Hmmm you could check with your colleague your configuration between the machines. Maybe there is a difference with user permissions. If he has the same machine config (I assume this).

[Tim_D_haeyer]

Normally my machine should be in a “less restrictive” OU in our AD. Meaning that not all group policies apply to my machine. Mainly because I’m already developing in Visual Studio.
I don’t really know where to start looking for the issue. Any hints are welcome!

[Pablito (Pawel Wozniak)]

If you have access or contact with IT in your company maybe they could compare your account with your colleague account and their restrictions etc.

[Tim_D_haeyer]

I found the issue. I had an older version of NLog in the GAC of my machine. I replaced it with the newer version that ships with UiPath studio and it works.

[Pablito (Pawel Wozniak)]

Can you describe a little more. It’s interesting and I would like to know more in case of similar situation like this

[Tim_D_haeyer]

@Pablito Well I started looking a bit more in detail to the error messages that I saw in the event log. It was clearly pointing to NLog.
I’m a BizTalk developer myself and I have quite some things in the GAC of my machine because of that.
So I checked the version of the NLog DLL that was in the GAC (C:\Windows\Microsoft.NET\assembly\GAC_MSIL) and it seemed to be an older version than the one that is in the UiPath studio folder.
I put that version in the GAC and it works.

So this means that, allthough there is a dll in the UiPath Studio folder, it takes the one from the GAC at runtime. How the Runtime Locates Assemblies - .NET Framework | Microsoft Learn

Not sure if there is any way to force to use the local reference instead of the GAC. But your developers can probably find that out.

[Pablito (Pawel Wozniak)]

Is it possible that you have installed or updated GAC recently? What I’m thinking is that maybe library was registered on top of the UiPath’s library during installation/update.
