File “UiPath.Agent.exe” open robot following some error, but robot of old version is running normalc3 (Blue is old version and red is new version).
Anyone solve it or new solution for this?

Hi @sang96011

Welcome to the Community!!
As I have experienced the posts posted by some users, having multiple versions of the UiPath studio can run into issues. Please delete the older version first and make sure you delete all files under below folder


Now, install a fresh installation of the new version. This should work for you.

Since now you have installed both versions, uninstall them both and try again…

Let know how it goes

If it works out for you, please make sure to mark the answer as the solution so it could help others too :slight_smile:


Thanks @Lahiru.Fernando,
It work, but I discovery that, new version don’t need service, it use a process name “UiParth.Service.UserHost.exe” for that.
