Hello Wonderfull people.  
I would really appreciated if you could help me with this problem:  
I downloaded Practice 1 - Extract Email Address without RegEx from UiPath website ( [Académie UiPath](https://academy.uipath.com/learningpath-viewer/8280/1/507678/30))

 ![image](https://global.discourse-cdn.com/uipath/original/4X/3/a/4/3a4b37d005542518273dd97ca8fe8464c0bae793.png)

And the i run the program. Everything is ok.

However, when i Copy the program to another UiPath instance and i run it, i received this message:

 ![image](https://global.discourse-cdn.com/uipath/original/4X/b/7/8/b785692e244e197d4b0365684040cb60168befeb.png)

I verified packages on,

Does somebody could help me to find what more do i have to check to troubleshoot why is not working when copying the original process?

Thanks in advance…

Hi,

This error is mostly caused by double quotation except `"` (0x22) in Windows project.  
Did you convert it to Windows project? If so, for now, can you replace all double quote with `"` in "Set input data " activity? (please copy and paste if necessary)

The following post will also help you.
