I'm currently trying to use Windows SIM to create a Windows 10 autounattend.xml file for a custom installation. I have a standard, generic, enterprise edition of Windows 10, which is my source for the wim file. I can't get Windows SIM to create the catalog. The error I get is just "failed to complete". I've rummaged around online and the only suggestion I can get is that SIM needs to be a 32-bit installation to generate catalogs for 32-bit or 64-bit Windows images, and a 64-bit installation of WIM can only generate catalogs for 64-bit Windows. I'm running a 32-bit system, and I'm trying to get a catalog for a 64-bit image, so there's shouldn't be a conflict here. Does anyone know how to get around this issue, or solve it? I can't even start creating an answer file until I manage to successfully generate a catalog for a WIM file.



I believe that you need a 64 bit "technician's machine" to work with 64 or 32 bit OS's. I don't think you can work with a 64 bit version on a 32 bit technician's machine. When you point SIM to a valid ISO file, it takes a while to create that catalog file, but it's impossible to proceed without it.
