I have a RED 10 that I've been using when with v17.5. When I first upgraded to v18 it worked until v18-MR2. I want to go back to using v17.5 but since I've updated from v18 to v18-MR2 I don't have a v17.5 firmware in my history.
I can't find the installer for v17.5 in mySophos portal. Is there a place where installers for the latest version of an older release are available?
