Hi everyone,
For windows the solution was found - one need to set registry key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Serif\Affinity\Photo\1]
"No Update Check"=dword:00000001
Can also be set via MSI property "NO_UPDATE_CHECK_PROPERTY" by assigning the value of "#1".
But there is no obvious solution for osx...
In the previous message there was an info about "network install tool" but I can't find any information about it...
Is there is any universal solution for Win and Mac to disable update notification availabe in 1.6.x now?
Thanks in advance.
