That sounds ok for me.
About Architecture detection: The Architecture returned by the VM's system
properties is always the architecture of the VM, not the architecture of the
processor. If you run a 32-Bit VM on a em64 Windows, windows emulates a
32-bit environment (like it did for 16-bit programs on 32-bit windows). The
VM has no chance to detect if this Hardware would support 64-bit.
Apart from that, the architecture returned IS exactly what you need, because
if you run in a 32-bit emulation you have to load the 32-bit dll's. On the
other hand, if you run in 64-bit mode, you have to load the 64-bit dll's.
If you don't deliver your installer with your own vm, you can not say in
advance with which VM your installer runs, since this depends on the setting
on the target machine. You may have both versions of the VM installed on the
target...
