I've been trying for a solid day to get this installed, and have had to work through many strange installation errors to no avail. I am running 64-bit Windows 7.
I'm attempting to install AutoCAD Architecture 2012 with a 32-bit "fix" provided by a 3rd-party software called Microvellum. I have run into a few errors which caused me to shuffle language files around and now I'm running into a more generic installation error 1603. I've attempted solutions from many forum posts, but still haven't been successful.
All installation files are local on the machine.
1. Uninstalled 64-bit installation of AutoCAD Arch 2012.
2. Downloaded Microvellum zip with x86 config changes.
3. Attempted install: No InventorFusion.msi file. -> Moved the msi file from the x64 folder to x86 folder.
4. Attempted install: No language files for AutoCAD or InventorFusion. -> Moved language files from x64 to x86 folder.
I suspect that any 3rd party "fix" that you have that will allow 32-bit to be installed onto 64-bit is not going to be supported. You should probably ask for assistance from the Microvellum company, since they provided the "fix."
