I have an MSI which installs a windows service as either LocalSystem ot
CustomAccount depending on what the user selects using a Condition.
Occasionally the MSI would fail to uninstall, the files were removed but the
service was not removed from the services.msc window. I have come up with
two potential causes and resolutions:
1) I created lots of these MSI's all based on each other and many of them
have the same Guid for the ServiceInstall Component. Does this cause issues
between two completely seperate MSI's? This kind of relates to why it only
happens very infrequently.
2) Whether an install is carried out using LocalSystem or Custom account is
determined by a value in a property called SERVICE_LOGON_TYPE which is set
by the user in the UI on install. However the MSI has no idea what this
value is when uninstalling, so do I need to save the SERVICE_LOGON_TYPE and
maybe the service username as a registry setting? If I do need to do this,
why does it work so often and only fail once in a while?
Code Below:
