Hi Rob - Your 'nothing' is probably more than my nothing on this topic, so thanks in advance for any assistance and insight you can provide.
Here's the relevant log segment: ********** ComPlusInstallExecuteCommit: Entering ComPlusInstallExecuteCommit in C:\WINDOWS\Installer\MSI29.tmp, version 3.7.1224.0 MSI (s) (E0!50) [11:17:57:286]: Closing MSIHANDLE (859) of type 790531 for thread 3920 MSI (s) (E0!50) [11:17:57:286]: Creating MSIHANDLE (860) of type 790531 for thread 3920 MSI (s) (E0!50) [11:17:57:286]: Closing MSIHANDLE (860) of type 790531 for thread 3920 MSI (s) (E0!50) [11:17:57:426]: Creating MSIHANDLE (861) of type 790531 for thread 3920 MSI (s) (E0!50) [11:17:57:426]: Closing MSIHANDLE (861) of type 790531 for thread 3920 MSI (s) (E0!50) [11:17:57:426]: Creating MSIHANDLE (862) of type 790531 for thread 3920 ComPlusInstallExecuteCommit: Registering assembly, key: myApp MSI (s) (E0!50) [11:17:57:426]: Closing MSIHANDLE (862) of type 790531 for thread 3920 MSI (s) (E0!50) [11:18:01:708]: Creating MSIHANDLE (863) of type 790531 for thread 3920 ComPlusInstallExecuteCommit: ExceptionInfo: Code='0', Source='System.EnterpriseServices', Description='Failed to load assembly 'c:\program files (x86)\MyCompany\queue\13.0\vmsqueue.dll'.', HelpFile='', HelpContext='0' MSI (s) (E0!50) [11:18:01:708]: Closing MSIHANDLE (863) of type 790531 for thread 3920 MSI (s) (E0!50) [11:18:01:708]: Creating MSIHANDLE (864) of type 790531 for thread 3920 ComPlusInstallExecuteCommit: Error 0x80020009: Failed to invoke RegistrationHelper.InstallAssembly() method MSI (s) (E0!50) [11:18:01:708]: Closing MSIHANDLE (864) of type 790531 for thread 3920 MSI (s) (E0!50) [11:18:01:708]: Creating MSIHANDLE (865) of type 790531 for thread 3920 ComPlusInstallExecuteCommit: Error 0x80020009: Failed to register .NET assembly MSI (s) (E0!50) [11:18:01:708]: Closing MSIHANDLE (865) of type 790531 for thread 3920 MSI (s) (E0!50) [11:18:01:708]: Creating MSIHANDLE (866) of type 790531 for thread 3920 ComPlusInstallExecuteCommit: Error 0x80020009: Failed to register assembly, key: myApp MSI (s) (E0!50) [11:18:01:708]: Closing MSIHANDLE (866) of type 790531 for thread 3920 MSI (s) (E0!50) [11:18:01:708]: Creating MSIHANDLE (867) of type 790531 for thread 3920 ComPlusInstallExecuteCommit: Error 0x80020009: Failed to register assemblies MSI (s) (E0!50) [11:18:01:708]: Closing MSIHANDLE (867) of type 790531 for thread 3920 MSI (s) (E0:20) [11:18:01:708]: Closing MSIHANDLE (858) of type 790536 for thread 3360 ********** Doesn't seem very helpful ... but that's what I've got ... If the assembly is re-based to target Framework v2 [2.0.50727, to be precise] ... then it installs just fine ... There is some uninstallation weirdness [but only on 1 system, not on a clean test box] - when uninstalling, the app remains in the Component Services control panel applet ... the installed files and folders [and ARP entry] get removed properly ... weird, huh? We're trying to move all of our code to Framework v4 ... so this is kind of a pain ... and as I've said already, any assistance / insights are greatly appreciated.
