I verified my file of zorin os it doesn't match what can I do?
If you have a mismatch on the Zorin OS .iso, you should go directly to the Zorin Link at the top of this page and download the copy of Zorin you need. Check the 256SHA and if all is well, proceed to burn your copy.
If this is an .iso you have already used to install Zorin OS, I highly recommend Reinstalling Zorin OS with a legitimate copy.
Also if it's Zorin 16 Pro that mismatch contact the Zorin brothers for a new download link.
