Hi,
Do you use CommunityEdition? If so, can you try the following step?
Windows project
First, create folder tessdata under c:\Users[AccountName]\AppData\Local\Programs\UiPath\Studio if it doesn’t exist.
Then put ara.traineddata file to the tessdata folder.
Finally, restart your Studio.
Windows Legacy project
First, create folder tessdata under c:\Users[AccountName]\AppData\Local\Programs\UiPath\Studio\net461 if it doesn’t exist.
Then put ara.traineddata file to the tessdata folder.
Finally, restart your Studio.
