Hello @Elancheran_E18

Please take a look at my suggested solution here:

Unable to install package / run automation

Hello @JavXult Can you please try and compare this file from your development machine, with the one on your production machine? C:\Program Files\UiPath\Studio\NuGet.config If the 2 files differ, then please try this: Take a backup of the file on your production machine Replace the file on your production machine with the file from your development machine Please let me know if it helps. I have created a case at UiPath Customer Support about this NuGet.config file that doesn’t get update…

Regards
Soren
