Can't open my project after killing Excel process

Hi @Oliver8, deleting the project.json from a project, then reopening the project by either double clicking a .xaml file or opening it via Open Project will recreate the project.json with the default dependencies available in that version (Meaning Excel, Mail, System and UIAutomation activities). This is the reason why @Shikhar_Tandon mentioned this alternative.
When do you receive a “UIPath says project.json is missing.” error?
Also, could you please give us some more details regarding this:

  1. I noticed the error is in French - is the Display Language in Windows French as well, or only Studio is in French?
  2. What Excel activity where you using when you killed the Excel processes?
  3. Does this happen only for one project or any project that you are currently trying to open?
  4. Could you please generate a DiagnosticsTool report, via the steps provided here, and then either send it to me or @pablito or @loginerror in a private message: Studio Community installation progress gets stuck - #13 by coramia
    Thank you!
