Adobe Reader failed to sign

Thank you for sharing the screenshot.

Did you try clicking on the "Aceptar" button?

Check if you can draw the box to add the signature as mentioned in the message box: "hold down the mouse button and drag the area of the document where you want the signature to appear."

You will need to press the hold the left button on the mouse and then drag it on the document and see if it creates a box. Once the box is created, click on that box to add the signature. 

Let us know how it goes.

Thanks,
