Just to follow up on my own message as I figured out the problem by looking in the source code - the guids passed in the EventCLSID and InterfaceID need to have the { } around them, as the strings are passed directly as-is to the complus administrator api.
Changing my wix accordingly works perfectly: <cpa:ComPlusSubscription Id="s4" Name="Subscriber4" MethodName="MyMethod" EventCLSID="{2B902A6B-D34A-4F2C-B06D-003D0FEEF358}" InterfaceID="{D54AEDED-63C5-42BD-9825-4FCB5E04A5AE}" Enabled="yes" Queued="no"/> Tim -------------------------------------------------------- This e-mail is for the use of the intended recipient(s) only.
