I currently am having an issue with a installer built with IS 10 installed on a Vista 64 Environment. It does not happen on all machines, just one machine has been reported.
Part of the Verbose Log: (Please note I have the same behavior with all managed custom actions)
Action start 12:56:25: Set_WebSites_Flatlist_AppCmd. MSI (c) (8C:2C) [12:56:25:424]: Invoking remote custom action. DLL: C:\Users\UsersName\AppData\Local\Temp\MSI8420.tmp, Entrypoint: m24 InstallShield: Loaded CLR successfully InstallShield: Managed code threw an unhandled exception. CustomAction Set_WebSites_Flatlist_AppCmd returned actual error code 1603 but will be translated to success due to continue marking Action ended 12:56:26: Set_WebSites_Flatlist_AppCmd. Return value 1.
Other Notes:
Now this method is wrapped in a try catch, meaning no code should throw an unhandled exception as long as the method is entered. I have ruled out virus scanner, he does have windows defender but I don't think this would matter.
I am running out of ideas what could cause this. Any Ideas? Is there something I should look for in the log file? Any help would be greatly appreciated?
If you haven't yet, you might try building your custom action assembly with your platform set to x86 instead of Any CPU or x64. There are limitations of our host which do not allow it to work with 64-bit assemblies.
