#2

Abhishek, could you post a script that you are trying to execute?


#3

Hi @ashapkina,
Thanks.
The OCR is solved now. Actually i was working on AWS server OS so because of that OCR was throwing error of dependencies. So i install RPA Express in local window , now its working.

But i am unable to import zip file in local window. I copied Control Tower from AWS server and paste in the same path USERS/USERS/Control Tower in local but its throwing error :

"Input file cannot be parsed: invalid format or not CSV file "


#4

@abhishek_panPC This error happens sometimes, we are investigating it now. The solution we have right now is to uninstall RPA Express, remove the Control Tower folder C:\Users\user\ControlTower and RPA Express folder, and then install RPA Express again.
Do you have any existing business processes that you need to save?


#5

@abhishek_panPC The workaround for this issue that we found it to run any business process in Control Tower, and then import a new package.
