Hi,
Do you already have trainneddata for your language? If yes, can you try as the following?
Windows project
First, create folder tessdata under c:\Users[AccountName]\AppData\Local\Programs\UiPath\Studio
if it doesn’t exist.
Then put xxx.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 xxx.traineddata file to the tessdata folder.
Finally, restart your Studio.
Regards,
