Hi RalphMoyle
I'm guessing you mean a post Classic version and the easiest option to prevent auto upgrade that I have seen on here is from Random_nuggets as follows:
" A simpler, more surgical method is as follows:
- a) Open the folder in which MYOB is installed. Typically this will be in:
C:\Users\<your username>\AppData\Local\Programs\MYOB\AccountRight
- b) Inside that folder you will find a program file named Update.exe. Simply rename this program file to, say, "Update-disabled.exe". Voila! No more updates!. When AccountRight is next started, it will fail to find its auto-update program, and then carry on running the software as is.
I have successfully tested this approach since the AR 2026.3 release (PC edition).
If this is not applicable to your version, then re-post on the Forum for an alternative as they are out there.
Cheers
