I found I could open and save 1-2-3 files after applying SP3 after following
these steps:
Step 1: Create these new registry nodes:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileOpenBlock
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\FileSaveBlock
Step 2:
In BOTH of them create this Dword entry:
LotusandQuattroFiles
leaving it at the default value of 0

You can also use the Policy node:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Excel\Security\
etc
This takes precedence over the others I posted.
