An existing directory is not an error, it's just assumed to be a standard
prefix. That's why creating a non-standard prefix requires the directory to be
missing.

If you want to force creation of a 32-bit prefix in an existing dir, you can
always create a dummy 32-bit system.reg. Of course this has races too if some
other process is starting in that dir...
