There are times when ArcFM AutoUpdater messages can interrupt some activities in ArcFM, such as during mass updates. AutoUpdater activity can be disabled for an individual computer through a registry change. The value name is AuNoMessages and can be found here:
HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > Miner and Miner > ArcFM8 > AUOptions > AuNoMessages
An AuNoMessages value of 0 is the default setting and allows AutoUpdater messages to be generated normally. Changing this value to 1 disables AU messaging for your current Windows install.
We tested and confirmed the above on Windows 10 and 2012R2, with ArcFM 10.2.1d SP1.
