Hi @majda_benouahi

Welcome to our UiPath Forum! :slight_smile:

Please see this post (and the links it contains) and go over the solutions they provide:

It is basically to reinstall Studio from the latest installer.

Hello,

Thank you for your response.

I did the steps as mentionned at least 5 times. But it didn’t change anything, i have also the same error.

Thanks for helping.

Is there a possibility that certain protection software is blocking access to either internet or Studio installation files under:

%userprofile%\AppData\Local\UiPath\app-19.5.0\UiPath

I had a similar issue, I did a clean install and had to update the nuget file located in AppData\Roaming…

Sorry I can’t remember the full path and it no longer appears on my computer :confused:

Thanks, i installed Microsoft Visual Studio and then it works. I think some librairies was missied on my machine and was fixed when installing MicrosoftVisual Studio.
