I have created a number of instance transforms in my WiX installer as below:
<!-- Non-Default instances --> <InstanceTransforms Property="APPINSTANCE"> <!-- These instances are for DIT, SIT and PROD --> <Instance ProductCode="4E7CC0E0-BECC-4e79-A626-20028B93C8C9" ProductName="MSS DAO Windows Service" Id="DAO_Instance"/> <Instance ProductCode="3F164DA9-8C57-49e9-9346-A06DA9B5580D" ProductName="MSS EMEA Windows Service" Id="EMEA_Instance"/> <Instance ProductCode="35646A8B-F991-44b1-AAE8-57DF08B30272" ProductName="MSS APJ Windows Service" Id="APJ_Instance"/> <!-- These instances are for UAT - special case becuase they may exist on same servers as SIT instances --> <Instance ProductCode="14CAA264-8CF9-48d8-B174-0A5B298C561E" ProductName="MSS DAO UAT Windows Service" Id="DAO_UAT_Instance"/> <Instance ProductCode="CD94A497-0091-4522-AD60-E21A7CFBDFF0" ProductName="MSS EMEA UAT Windows Service" Id="EMEA_UAT_Instance"/> <Instance ProductCode="2D226523-ADF4-40fa-BA1E-624FE84EF1CF" ProductName="MSS APJ UAT Windows Service" Id="APJ_UAT_Instance"/> </InstanceTransforms> When uninstalling one of these non-default instances, I need to make sure that my custom actions get run. Most of the time I will be leaving other instances on the machine. <Custom Action="CleanupDataFiles" After="InstallFinalize">Installed</Custom> This custom action does not run when uninstalling with msiexec /u TRANSFORMS="EMEA_Instance ... However, the rest of the app instance gets uninstalled fine. Does someone know the correct condition to use? On a related note when GACd assemblies and shared COM objects are removed for one instance, does the MSI and/or windows keep a usage count so that other instances are not broken?
