Update failure for Photoshop CS6 and PhotoshopCC for photographers. This has happened several times. According to the error code, the update for Photoshop the other day showed that the update was corrupted. Doesn't Adobe pay attention anymore?
You need to provide some details so we can help you. What version do you have? What updates are you trying to install? What are the full error messages that you see when attempting to update?
A corrupted update means that something failed on your local disk or network. The Adobe servers are checked constantly to prevent file corruption and malware, and the updates on the servers are highly unlikely to be corrupt.
