Hello Isabel Martinez-Lacaci

Unfortunately, the error message you receive is too generic for me to provide an accurate answer. The issue might be caused by the .net installation you have on your computer, or by a corrupt Studio component.

My advice is to try to repair Studio from “Control Panel\All Control Panel Items\Programs and Features”. If the issue persists even after the repair, please raise a Support Case via this web-form: gateway.sdl.com/webtocase and one of our engineers will contact you in order to have the issue addressed. Please let me know what the Support Case number is, if you have to log one.

Thank you.
