CE 2018.1 - Could not load file or assembly 'Newtonsoft.Json when starting new "Agent Process Improvement"

On yesterday installed UIPath Studio CE,

  • when trying to start a new project based on “Agent Process Improvement”
  • I receive the following messageal iniciar nuevo “Agent Process Improvement”


Could not load file or assembly ‘Newtonsoft.Json,
Version=, Culture=neutral,
PublicKey Token = 30ad4fe6b2a6aeed’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference.
(Exception from HRESULT: 0x80131040)

After that, if I press “Ok”, the process just continues, and works (apparently, fine)

Maybe this is an issue regarding this version (2018.1)?

the same problem…

At some point in Friday, the CE already activated started working as it should.
But, until today, another CE installation keeps failing Activation.

At first, I supposed the Activation Server had issues, but my thoughts have no other backup nor answer to the issue.

As of now:

  • First CE activated, which has issues on Friday, is working.
  • Second CE does not activate at all

Hope this can be solved somehow.
