Thanks Phill and Rob. This is indeed a per-machine install.
The issue does appear to be due to resources related to the user profile not being available to the managed bootstrapper. I have verified that the error occurs when there is no logged in user, though not every single time. I have narrowed it down to a combination of two things, not necessarily inclusive: (a) The service leaving orphaned handles to the user registry hive and (b) the windows user profile service proactively killing any user registry hive handles that the service has left open for the bootstrapper to use. So far restarting the service seems to mitigate the issue, I believe by clearing out any orphaned registry handles, before the bootstrapper is invoked. An alternate solution may be to create the process using the native C++ call via P/Invoke and letting the child process inherit handles (the .NET call doesn't seem to allow users to explicitly specify inheritance of handles). This should prevent the user profile service from detecting the registry handles as orphaned and allow the bootstrapper to use the user profile's resources as needed. I am continuing to work through this issue. Will post here as and when a definitive solution is found. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Managed-Bootstrapper-fails-to-load-Errror-0x80040150-tp7591316p7591347.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
